A cross-metathesis process for preparing an α,ω-functionalized olefin, such as methyl 9-decenoate, and an α-olefin having three or more carbon atoms, such as 1-decene. The process involves contacting in a first reaction zone an α-functionalized internal olefin, such as methyl oleate, and an α-olefinic monomer having three or more carbon atoms, such as 1-decene, with a first metathesis catalyst to prepare an effluent stream containing the α,ω-functionalized olefin, such as methyl 9-decenoate, an unfunctionalized internal olefin, such as 9-octadecene, unconverted reactant olefins, and optionally, an α,ω-difunctionalized internal olefinic dimer, such as dimethyl 9-octadecen-1,18-dioate; separating said effluent streams; then contacting in a second reaction zone the unfunctionalized internal olefin with ethylene in the presence of a second metathesis catalyst to obtain a second product effluent containing the α-olefinic monomer having three or more carbon atoms; and cycling a portion of the α-olefinic monomer stream(s) to the first zone.

Latex compositions containing ethylenically unsaturated esters of fatty compounds and applications thereof
Novel latex or emulsion compositions containing internally plasticizing and crosslinkable monomers derived from traditional semi-drying or non-drying oils are disclosed and claimed. The monomers are ethylenically unsaturated derivatives of long-chain olefinic compounds. Preferred embodiments include latex formed from acrylate or methacrylate esters of fatty alcohols. A process for the synthesis of the latex composition is also disclosed, which involves (a) polymerization of the ethylenically unsaturated derivatives of a long-chain olefinic compound in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from -5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These compositions are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.

InactiveUS7125950B2Overcome deficienciesFatty oils/acids recovery from wasteSugar derivativesPolyesterNatural source
A solvent-free process for making a polyol fatty acid polyester composition useful for preparation of polyurethanes is described. These compositions are preferably made by reaction of a natural oil (from plant or animal) with a multi-functional hydroxyl compound derived from a natural source, such as sorbitol, in presence of an alkali metal salt or base such as potassium hydroxide as a catalyst which also acts to saponify the reaction mixture. The hydroxyl content of the prepared composition depends on the amount of the multi-functional hydroxyl compound used in the preparation. In another embodiment, the hydroxyl groups of these compositions are reacted with an isocyanate, such as the polymeric diphenylmethane diisocyanate (also known as 4,4′-diphenyl methane diisocyanate, or MDI) to form polyurethanes in a conventional manner.

Provided are a glyceride oil composition derived from a fish oil and a preparation method thereof. The composition includes docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) with a content of 45 to 95% by weight and eicosapentaenoic acid (EPA) with a content of 0.001 to 13% by weight among constituent fatty acids, and a saturated fatty acid having 16 to 18 carbon atoms, which is bonded at 1- and 3-positions, with a content of 0.001 to 5% by weight among constituent fatty acids, in which a weight ratio of docosahexaenoic acid (DHA) / docosapentaenoic acid (DPA) is 0.5 to 8 and a weight ratio of docosahexaenoic acid (DHA) / eicosapentaenoic acid (EPA) is 3.5 to 15. The glyceride oil composition derived from fish oil has nutritional and physiological superiority due to containing a great amount of polyunsaturated fatty acids such as DHA and DPA in a form of glyceride, and can minimize disadvantages of EPA such as inhibition of ω-6 fatty acid metabolism by containing a low amount of EPA. The glyceride oil composition is excellent in digestion and absorption of polyunsaturated fatty acids into a human body by containing a low amount of saturated fatty acids at 1- and 3-positions and process characteristics such as an oxidation stability and water-dispersibility.
