Description

TITLE CATALYTIC PROCESS FOR PREPARATION OF HYDROFLUORO(ETHER)OLEFINS FIELD

[0001] The present invention relates to processes to prepare fluoroolefins fromsaturated hydrofluoro(ether)halides. BACKGROUND OF THE INVENTION

[0002] The perpetual uncertainty in energy supplies and prices and a growingpublic awareness of the environmental impacts from the extraction, transportation and use of fossil fuels are motivating a renewed interest in low temperature heat utilization (i.e. heat at temperatures lower than about 300°C). Such heat may be extracted from various commercial, industrial or natural sources. Elevation of the temperature of available heat through high temperature mechanical compression heat pumps (HTHPs) to meet heating requirements and conversion of the available heat to mechanical or electrical power through Organic Rankine Cycles (ORCs) are two promising approaches for the utilization of low temperature heat.

[0003] ORCs and HTHPs require the use of working fluids. Working fluids withhigh global warming potentials (GWPs) currently in common use for HTHPs and ORCs (e.g. HFC-245fa) have been under increasing scrutiny culminating in the landmark HFC amendment to the Montreal Protocol recently agreed upon in Kigali, Rwanda. There is an increasing need for more environmentally sustainable working fluids for HTHPs and ORCs, especially given that environmental sustainability is a primary motivation for low temperature heat utilization. More specifically, there is a need for low GWP working fluids with boiling points higher than about 50°C that are particularly suitable for conversion of heat available at temperatures approaching or exceeding 200°C to power and for heating at temperatures approaching 200°C from heat available at lower temperatures. Even more specifically, a low GWP working fluid with a boiling point close to that of ethanol (78.4°C) could be advantageous as a replacement of ethanol in ORC systems for heavy duty vehicles (e.g. trucks) especially in Europe. Such a fluid could also be used as a solvent and as a heattransfer fluid for various applications, including immersion cooling and phase change cooling (e.g. of electronics, including data center cooling).

[0045] Disclosed herein are processes for improving the synthesis ofhydrofluoro(ether)olefins from the dehalogenation of a precursor saturated hydrofluoro(ether)haloalkane, e.g., perfluoroalkyl bromides and iodides. The precursor is obtained though isomerization and then dehydroiodinated using a glycol phase transfer catalysts instead of organo-ammonium or organo-phosphonium salts, which provided unexpectedly high yields of the hydrofluoro(ether)alkenes (aka hydrofluoro(ether)olefins).

[0046] For purposes of clarity, certain terms used herein are defined.

[0047] As used herein the term “dehydrohalogenation” refers to loss of HX,wherein X = I, Br, or Cl but not F.

[0048] As used herein the terms “alkane” and “alkyl” shall be understood to includeboth branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms. For example, C1-C8, as in “C1-C8 alkyl” is defined to include groups having 1, 2, 3, 4, 5, 6, 7, or 8 carbons in a linear or branched arrangement. For example, “C1-C8 alkyl” specifically includes methyl, ethyl, n-propyl, i-propyl, n-butyl, t-butyl, i-butyl, pentyl, hexyl, heptyl, octyl, and so on. In an embodiment, if the number of carbon atoms is not specified, “alkyl” refers to C1-C8 alkyl and in a further embodiment, “alkyl” refers to C1-C6 alkyl.

[0049] As used herein the term “olefin” shall be understood to mean a C3-C8 orhigher alkene.

[0050] As used herein the term “fluoroolefin” shall be understood to mean a C3-C8or higher olefin that incorporates at least one CF3 group.

[0051] As used herein the term “aqueous and / or alcoholic base” shall beunderstood to mean an alkali metal base. Non-limiting examples include KOH and NaOH and LiOH. When a crown ether is selected as the oxygen-containing catalyst the crown ether is compatible with the alkali metal of the alkali metal base. Such selections are known to those skilled in the art.

[0052] As used herein the term “phase transfer catalyst” shall be understood tomean a catalyst that facilitates the migration of a reactant from one phase intoanother phase where reaction occurs, such as the oxygen-containing catalysts described herein.

[0053] The hydrofluoro(ether)alkenes derived from and halo-fluoroalkanes andhalo-fluorooalkane ether s disclosed herein can be used as a heat transfer medium, working fluid, along or combined with other components suitable for use as the heat transfer medium or working fluid to carry heat to and from a source. Such heat transfer compositions may also be useful as a refrigerant in a cycle wherein the fluid undergoes a phase change; that is, from a liquid to a gas and back, or vice versa. Examples of heat transfer systems include but are not limited to air conditioners, freezers, refrigerators, heat pumps, water chillers, flooded evaporator chillers, direct expansion chillers, walk-in coolers, high temperature heat pumps, mobile refrigerators, mobile air conditioning units, electric storage cooling systems, battery cooling, immersion cooling systems, data-center cooling systems, and combinations thereof.

[0054] In some embodiments the fluid can be used for immersion cooling is usedto cool electronic devices, such as datacenter servers, insulated-gate bipolar transistor (IGBT) devices, telecommunication infrastructure, military electronics, televisions (TVs), cell phones, monitors, drones, automotive batteries, powertrains for electric vehicles (EVs), avionics devices, power devices and displays. Immersion cooling systems are heat transfer devices wherein there is no compressor, and the heat transfer medium possesses suitable dielectric properties. Generally, the object to be cooled is at least partially immersed in (in direct contact with) the heat transfer fluid contained in a vessel. In some embodiments, the heat transfer fluid may evaporate and condense in the vessel. In other embodiments, there may be no phase transition involved.

[0055] As use herein, a refrigerant is a compound or mixture of compounds(blend) that function as a heat transfer fluid in a cycle wherein the fluid undergoes a phase change from a liquid to a gas and back.

[0056] As used herein, the terms “comprises,” “comprising,” “includes,” “including,”“has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but mayinclude other elements not expressly listed or inherent to such composition, process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0057] The transitional phrase “consisting of” excludes any element, step, oringredient not specified. If in the claim such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consists of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

[0058] The transitional phrase “consisting essentially of” is used to define acomposition, method that includes materials, steps, features, components, or elements, in addition to those literally disclosed provided that these additional included materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention, especially the mode of action to achieve the desired result of any of the processes of the present invention. The term ‘consisting essentially of’ occupies a middle ground between “comprising” and ‘consisting of.’

[0059] Where applicants have defined an invention or a portion thereof with anopen-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also include such an invention using the terms “consisting essentially of” or “consisting of.”

[0060] Also, use of “a” or “an” are employed to describe elements and componentsdescribed herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

[0061] Further, when an amount, concentration, or other value or parameter isgiven as either a range, preferred range, or a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all rangesformed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. Where a range of numerical values is recited herein, unless otherwise stated, the range is intended to include the endpoints thereof, and all integers and fractions within the range. It is not intended that the scope of the invention be limited to the specific values recited when defining a range.

[0062] Unless defined otherwise, all technical and scientific terms used hereinhave the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present invention, suitable methods and materials are described below. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety, unless a particular passage is cited. In case of conflict, the present specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting.

[0063] The precursor or starting materials disclosed herein were generallyproduced in accordance with Step 1-3, illustrated by Scheme 1 (given below), or when possible acquired commercially. Scheme 1. Preparation of C2F5CH=CHC2F5 (153-10mczz) – steps1-4. Control Experiments. Preparation of C2F5CH=CHC2F5 (153-10mczz).

[0064] A first control experiment was conducted using 20 ml sample vials, 10 ml ofcommercially available 45% aqueous KOH solution; 3.1 g (0.008 mol) of C2F5CH2CHIC2F5 without any catalyst at ambient temperature. Starting materialswhere distilled to a purity ~ 92-95%, KOH – 45 wt. % solution in water; commercial solution, Aldrich). Conversion after about 18 hrs. was 10%.

[0065] The control experiment was repeated using 2.0 g of C2F5CH2CHIC2F5, 10ml of commercially available 45 wt% KOH solution, without a catalyst at 65°C. Conversion was poor at - 4.5% after 2.5h, - 5.2% after 3h, and ~21.3% after 19h.

[0066] Additional control experiments were conducted to compare ammonium andphosphonium salts as PTCs. The reaction of C2F5CH2CHIC2F5 was carried out using a KOH (45 wt.%, water solution) in the presence of PTC such as, an ammonium R4N+X- (R= C4H9, X=Cl, Br, HSO4-) or R4P+X- (R=C4H9, C6H5, X=Br, Cl) salts at 25- 40°C. The reaction of C2F5CH2CHIC2F5 in the presence of tetrabutylammonium hydrogen sulfate catalyst at 25oC had a conversion of ~ 20% after 16h, with tetrabutylphosphonium bromide at 40°C the conversion of C2H5CH2CHIC2F5 was 60- 70%, but reaction mixture was very dark.

[0067] A further control dehydrohalogenation of C2F5CH2CHIC2F5 was conductedusing a mixture of 140 ml of 45 wt.% KOH, 3.8 g Aliquat®R336 and 50 g C2F5CH2CHIC2F5. The KOH / Aliquot 336 mixture was preheated to about 50°C. The C2H5CHIC2H5 was added and while the temperature was gradually increased to 110°C, and C2F5CH=CHC2F5 (153-10mczz) was distilled off. The yield of 153- 10mczz (purity >95%) was 65%.

[0068] In view of the control experiments, a need exists to increase both the yield,purity, and E / Z ratio of the hydro(ether)fluoroolefin (e.g. 153-10mczz, F13iE), withhigher conversion of hydro(ether)fluorohaloalkane to desired isomer. As disclosed herein, it was unexpected that dehydrohalogenation of hydrofluoro(ether)haloalkane in the presence of certain glycols, as phase transfer catalysts, would significantly improve conversion and yield of hydro(ether)fluoroolefin, such as C2F5CH=CHC2F5(153-10mczz) by, e.g., 10%, 20%, 30% or higher, and the ratio of E / Z isomers.EXPERIMENTS

[0069] The experiments described herein were performed using 20 ml glasssample vials equipped with caps and plastic inserts (which limit heating to 70°C), containing 10-13 ml of an aqueous MOH solution, e.g., KOH, 0.1-1g of catalyst and about 2-6 g of a C2F5CH2CHIC2F5 precursor (~96-98% purity). The vial contentswere vigorously agitated, e.g., at 1500 rpm product was transferred into -78oC cold trap under vacuum and analyzed by NMR and GC / MS . Scale-up reactions were conducted in heat regulated, multi-neck flasks, (250 ml, 500 ml, 1000 ml ot 2000 ml) to facilitate temperature measurement, provide a vacuum controlled distillation head, and control feed of the precursor reactant.

[0104] The reaction was carried out in a 250 ml three-necked round bottomedglass flask, equipped with a distillation head (containing 40 cm Vigreux section), thermocouple well and a heavy magnetic stir bar. To the flask containing vigorously agitated mixture of 100 ml 45 wt. % KOH solution in water and 1 g (0.0025mol, 1.25 mol %) of PEG 400 it was added dropwise 80g (0.2 mol) of (CF3)2CFCH2CH2I at ambient temperature over 30 min period. During the addition an internal temperature slowly increased up to 35oC over 30 min period, then started to drop. The NMR ofthe organic layer after 30 min indicated 55% conversion; after 1h 40 min. at 28°C; and 66% after 3 hrs. The temperature of the reaction mixture was slowly increased to 90°C over a 2 h period and (condenser temperature of the distillation head was set to 10°C) and distilled product was collected as a liquid into receiver chilled with wet ice. Product, 50g of crude material b.p.25-26°C was isolated. The isolated product had a small amount (~0.5g) of water and was dried over MgSO4. A clear liquid based on NMR contained 98% of (CF3)2CFCH=CH2 and 2 % of starting material. The isolated yield was 92%.

The temperature of distillation head condenser was maintained at 5°C and the product was collected in round bottom receiver, chilled by wet ice and in the -78°C cold trap. The reaction mixture was heated to 37°C and 216 grams of C2F5CH2CHIF were added dropwise using the addition funnel. Since the reaction was slow, an additional portion of 3g, 4g and 3g of tetraethylene glycol were added during the course of the reaction. The product was collected in a cold receiver (38.8 grams) and a cold trap (54.7 grams) to provide a combined product (total weight 93.5g, 77% yield, purity 98 wt. %, 2 wt. % - startingmaterial) and distilled to give 88.8g (yield 73%).

[0124] A 500 ml three neck flask equipped with a thermocouple, heavy magneticstir bar, an addition funnel and distillation head equipped with 40 cm with Vigreux column, was loaded with 120 ml of 45 wt. % KOH solution in water, 1g (0.0067 mol) of TrEG (triethylene glycol) and 80 g C2F5CH2CHIC2F5 (97% purity, 0.197 mol). The KOH / TrEG reaction mixture was first preheated to 65°C and C2F5CH2CHIC2F5 was added slowly, over a 1h period and the product (153-10mczz) was distilled simultaneously and collected as a liquid in a receiver cooled using ice bath. The flask temperature was brought up to 65°C and 153-10mczz started to distill over about 2.5 h, with the flask temperature of 65°C to 105°C. The product with a b.p. of 47-50°Cwas collected into cold (wet ice) receiver and 43.8g of crude 153-10mczz (expected 52.3g) was isolated. The yield of 153-10mczz was 84% with a purity of 99% (1% C2F5CH2CHIC2F5 + di-adduct). The E / Z isomers of 153-10mczz- ratio was ~ 95:5.

[0125] The reaction was scaled up, using 567 g of crude C2F5CH2CHIC2F5 (purity79 wt %) starting material. Fig.12 shows the 1H NMR spectra taken of the isolated153-10mczz produced in this Example 15. Example 16. Preparation of C2F5CH=CHC2F5 Using Starting Material of 75% purity. C2F5CH2CHIC2F5 + KOH→C2F5CH=CHC2F5 + KI

[0126] 650 mL of 45 wt % KOH solution in water was combined with 19 g oftriethylene glycol in a 2000 ml three neck round bottom flask equipped with a thermocouple, heavy magnetic stir bar, an addition funnel and distillation head containing 40 cm with Vigreux column. The flask was preheated to 62°C and then 455 g of C2F5CH2CHIC2F5 (purity of 75%) was added dropwise. The flask was kept above 65°C during the addition so the column was under reflux (started at a pot / flask temperature of 68°C and head temperature of 42°C, respectively) while C2F5CH2CHIC2F5 was still being added. Product was collected as a liquid in a pre- chilled (wet ice) receiver. Collection of the product happened mostly when the pot temperature was 63°C and the head temperature was 43°C. When addition of the C2F5CH2CHIC2F5 was complete the pot temperature was 66°C and the head temperature was 44°C. The product was washed with ice cold water and stored overmagnesium sulfate. The product (296g, 87% yield) was identified by 1H, 19F NMRand GC / MS as C2F5CH=CHC2F5 (mixture E- and Z- isomers, ratio 97:3). E-C2F5CH=CHC2F5,19F NMR (CDCl3): -85.02 (3F, t, 1.4 Hz), -117.84 (2F, dq, 7.4, 1.4Hz) ppm; 1H NMR (CDCl3): 6.26(t, 7.4 Hz) ppm. Z-C2F5CH=CHC2F5, 19F NMR(CDCl3): -85.22 (3F, t, 1.2 Hz), -112.36(2F, dd, 5.7, 7.4 Hz) ppm; 1H NMR (CDCl3):5.99 (m) ppm.Example 17. Synthesis of C2F5CH=CHC2F5 Using Starting Material Containing C2F5I.

[0127] Crude product (C2F5CH2CHIC2F5) contained residual perfluoroethyl iodide(PFEI) (up to 45 wt%) and in order to avoid additional steps involving distillation to remove PFEI and other impurities (including acetone, and others), a number of experiments using C2F5CH2CHIC2F5 product containing 35-45 wt.% of PFEI and other by-products were performed. Example 16 provides a typical procedure used for these experiments.

[0128] A 500 ml flask equipped with thermocouple, gas inlet tube, distillation headcontaining 40 cm with Vigreux column and connected to -78°C cold trap and N2 blanket was charged with 180 ml 45 wt. % aqueous KOH solution, 2.35 g of TrEG catalyst. The KOH / TrEG reaction mixture was vigorously agitated using heavy magnetic stir bar and preheated to 45°C. Crude C2F5CH2CHIC2F5 (270 g, purity 36wt. %; contained 46 wt.% of C2F5I, 18 wt. % others) was slowly fed into the flask from an inverted cylinder using an inlet tube. The reaction temperature increased to 50°C and temperature was maintained through addition. The temperature of the reflux condenser was set to 14°C, resulting in C2F5I being flash distilled and collected in the cold trap. The addition of 270 g of crude C2F5CH2CHIC2F5 took about 3h. The reaction mixture turned light brown in color and the head temperature during addition (mild reflux) stayed at 20-22°C.

[0129] After the addition of the 270g was finished, the reaction mixture was kept at55-62°C, while low boiling material was collected using a -78°C cold trap. A total of 138g material was collected, which was determined by NMR to be a mixture of 13 wt% (16.6g), 153-10mczz and 86 wt. % PFEI and small amount of perfluorobutane (C4F10). At a pot temperature of 62°C, the collection of liquid fraction was started. The head temperature slowly went up to 47-50°C while the pot temperature was increased from 62°C to 114°C over a 1.5-hour period, collecting 44.5 g of liquid, wet product, which was dried over MgSO4. NMR and GC analysis of crude productindicated the presence of E- and Z- 153-10mczz isomers of C2F5CH=CHC2F578.8and 3.4 wt. %, C2F5I = 9.7 wt %, and (C2F5CH2)2 - 8.1wt.%. The ratio ~ E / Z isomersof C2F5CH=CHC2F5 was 96:4. The combined yield of C2F5CH=CHC2F5 was 83.4%.Example 18. Isolation of Z-C2F5CH=CHC2F5 by Distillation

[0130] A sample of heels obtained after batch distillation of crudeC2F5CH=CHC2F5 was analyzed by GC (TC detector, ). Crude material contained41.45% of E- C2F5CH=CHC2F5, 15.2 % of (C2F5CH2)2, 20.7 % of Z-C2F5CH=CHC2F5,9% C2F5CH2CHIC2F5, 4.7 % C2F5CH2CH2I as major components. Crude materialwas fractionated using a 20 plates glass column equipped with distillation head and all fractions were analyzed by GC (TCD, wt.%) and NMR. A total of 1319.3 grams of the heel sample was distilled. The temperature of the condenser was set to 15°C and the reflux ratio was ~30:1 for the entire distillation.

[0132] As a result of distillation, a relatively pure Z- isomer of 153-10mczz(Fraction 15, purity 95%, 170 g) was isolated. A boiling point of Z-isomer wasestimated to be 70.5-71.5°C, which is substantially higher compared to E-isomer(b.p.48°C). Example 19.
