| titleOfInvention | A kind of preparation and purification method of trimethylolpropane fatty acid three ester |
| abstract | The invention discloses a kind of preparation and purification method of trimethylolpropane fatty acid three ester.The method comprising the steps of: with fatty acid methyl ester and TriMethylolPropane(TMP) for raw material, add basic catalyst, carry out transesterification reaction under vacuum, obtain transesterification reaction mixture; Add phosphoric acid solution, neutralization reaction removing basic catalyst; After reaction terminates, stratification or centrifugal layering, wash upper strata oil reservoir hot water, then by standing separation or centrifugation, obtain oil reservoir and water layer; Dehydrated under vacuo by oil reservoir, by the method for wiped film molecular distillation, gained heavy phase is the trimethylolpropane fatty acid three ester product of purifying, the fatty acid methyl ester of gained gently mutually for reclaiming.In reaction product of the present invention, trimethylolpropane fatty acid three ester content is high, accounts for more than 95%; Adopt molecular distillation purifying trimethylolpropane fatty acid three ester also to reclaim excess fatty acids methyl esters, can raw material availability be improved, and can purified product at a lower temperature. |
