Problems solved by technology

[0004] The preparation process of epoxy biodiesel is mature. Epoxy biodiesel is an excellent substitute for traditional fine chemicals. It reduces iodine value, improves oxidation stability, and improves lubrication performance, but its low temperature performance has not been improved. Its practical application is largely limited

Embodiment 1

[0025] Weigh 68g ethanol and 6g immobilized heteropolyacid catalyst PW 12 / SiO 2 Put it in a four-necked flask with a condenser tube and a thermometer, heat it to 30°C under stirring, then add 200g of epoxidized soybean oil fatty acid methyl ester, and record the initial epoxy value of the reaction system as 5.46, and at this temperature ring-opening reaction. During the reaction process, samples were taken every 30 minutes, and the epoxy value was measured. When the epoxy value was less than 0.08 (t=4.5h), the reaction was stopped. The above solution is cooled to room temperature, and the immobilized heteropolyacid catalyst PW is recovered by suction filtration. 12 / SiO 2 , the filtrate was placed in a separatory funnel, washed with alkali and water until pH = 7, and then distilled under reduced pressure to finally obtain a clear and transparent isomerized oil alcohol ether.

Embodiment 2

[0027] Weigh 84.4g of isopropanol and 6g of solid-loaded heteropolyacid catalyst TPA / SBA-15 and put them in a four-necked flask with a condenser tube and a thermometer, heat to 30°C under stirring, then add 200g of epoxy rapeseed oil Fatty acid methyl ester, the initial epoxy value of the reaction system was measured to be 5.46, and the ring-opening reaction was carried out at this temperature. During the reaction process, samples were taken every 30 minutes, and the epoxy value was measured. When the epoxy value was less than 0.08 (t=5h), the reaction was stopped. The above solution was cooled to room temperature, and the immobilized heteropolyacid catalyst TPA / SBA-15 was recovered by suction filtration. The filtrate was placed in a separatory funnel, washed with alkali and water until pH = 7, and then distilled under reduced pressure to finally obtain a clear and transparent Isomerized fatty alcohol ether.

Embodiment 3

[0029] Weigh 114.4g n-butanol and 7g immobilized heteropolyacid catalyst SiMo 12 / C is put in the four-necked flask that has condenser tube and thermometer, is heated to 35 ℃ under stirring state, then adds 200g epoxy castor oil fatty acid methyl esters, records the initial epoxy value of reaction system 5.46, and in The ring-opening reaction proceeds at this temperature. During the reaction process, samples were taken every 30 minutes, and the epoxy value was measured. When the epoxy value was less than 0.08 (t=4h), the reaction was stopped. Above-mentioned solution is cooled to room temperature, reclaims solid-loaded heteropolyacid catalyst SiMo through suction filtration. 12 / C, put the filtrate in a separatory funnel, wash with alkali and water until pH = 7, and then distill under reduced pressure to finally obtain a clear and transparent isomerized oil alcohol ether.

Abstract

The invention belongs to the technical field of lubricant modification technique, and particularly relates to a preparation method for alcohol ether type environment-friendly lubricant base oil. The preparation method comprises the steps: putting fatty alcohol and supported heteropoly acid catalyst into a four-neck flask with a condensed pipe and a thermometer, stirring and backflowing under the heating condition, then adding epoxy biodiesel, carrying out ring-opening reaction under the heating condition, determining the epoxy value of a reaction system in the reaction process, stopping reaction when the epoxy value is less than 0.08, cooling the reaction system to room temperature, performing suction filtration to recover the supported heteropoly acid catalyst, putting the filtrate into a separating funnel, washing to be neutral, and then performing decompression distillation, finally to obtain isomerized grease alcohol ether.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil modification technology, and in particular relates to a preparation method of alcohol ether type environment-friendly lubricating oil base oil. Background technique [0002] The requirements of modern mechanical equipment for lubricating oil are: (1) environmentally friendly, non-toxic, and biodegradable; (2) have high oxidation resistance and long service life; (3) require low pour point, High viscosity index, suitable for special occasions under severe cold and high temperature conditions; (4) Easy to synthesize oils of different viscosity grades. [0003] It can be seen that lubricating oil plays an extremely important role in the lubrication of equipment, usually mineral oil, synthetic oil, animal and vegetable oil, etc. Among them, mineral oil is used in the largest amount. Because of its low price and performance meeting the lubrication requirements of most equipment, it occupies a ...
