Epoxy low-polyether glyceride plasticizer and preparation method thereof

[0023] Example 1:

[0024] Ingredients: soybean oil, glycerol, sodium hydroxide, formic acid, hydrogenated water, concentrated sulfuric acid

[0025] The ratio of soybean oil, glycerol is 2% by 2: 1 ingredient and put into the reactor, adding 1% sodium hydroxide in the material of the feedstock, warmed to 190 ° C under nitrogen protection, reflow reaction for 8 hours; add 0.5 % Catalyst, use the distillation device and increase the reaction temperature to 50 ° C etherified to anhydrous production, at which time the product is a mixture of monoether glycerol esters and bisyl glycerides (if etherified The same acetic anhydride is used in whole can be used. The same as the following conventional operation, etc., the amount of hydrolytic acid and the mass of 10% to 50% of the low polyether glycerylate account for 0.5% to 1% of concentrated sulflic acid, Heating to 40 to 60 ° C, 0.9 ~ 1.4 times of hydrogen oxygen, dripped over 40 minutes, and the reaction was 10 to 65 ° C for 3 to 5 hours. After cooling, the water was then removed by alkali washing, water washing, distillation, and the like were obtained. The epoxy oligomerglyceride (content was higher than 80%, the same).

[0027] Ingredients: rapeseed oil, glycerol, potassium hydroxide, 3-chlorine oxide, dichloromethane Download Adobe Reader

[0028] The ratio of rapeseed oil, glycerol is 1.6%. The reactor is added and the reactor is put into the reactor, and the potassium hydroxide from 1.2% of the material oil is added, and the temperature is raised to 180 ° C under nitrogen protection, reflow 10 hours; add addition 0.6% of the catalyst, the distillation device and elevated the reaction temperature to 250 ° C etherified to anhydrous production, at which time the product is a mixture of monoether glycerol esters and bietherglycerides; And, water washing and other conventional amount of 3-chlorine oxide chloroform acid dichloromethane solution, 5 to 4 hours at 30 ° C after 5 ° C, and finally wash, wash, dehydrated by alkaline, washing, dehydration Epoxy oligoether glyceryl products can be obtained.

[0029] Example 3:

[0030] Ingredients: oil, glycerol, potassium hydroxide, formic acid, hydrogenated, p-toluenesulfonic acid;

[0031] The ratio of the oil and glycerol according to the amount of material is 3.2.2 is added and the reactor is put into the reactor, and the potassium hydroxide of 1.5% of the material oil is added, and the temperature is warmed to 190 ° C under nitrogen protection, reflow reaction for 9 hours; add 1 % Catalyst, use the distillation device and raise the reaction temperature to 245 ° C etherification to anhydrous production, at which time the product is a mixture of monoether glycerol esters and bisylglycerides; , After washing and other conventional operations, add 10% to 50% to 20% to 50% to p-toluenesulfonic acid by 0.5% to 1%, heated to 40 to 60 ° C, 0.9 ~ 1.4 times, 0.9 ~ 1.4 times. It was dripped in 40 minutes, and the reaction was 10 to 65 ° C for 3 to 5 hours. After cooling the temperature, the water is then passed through alkali washing, water washing, distillation, and the like, the epoxy oligomerglyceride is obtained.
