Abstract

The invention relates to a preparation method of epoxy aliphatic ester biological lubricant base oil. Metal ion supported cation exchange resin is used for a catalyst to prepare the epoxy aliphatic ester biological lubricant base oil. The preparation method of the epoxy aliphatic ester biological lubricant base oil is mild in reaction condition, high in catalyst activity, capable of reducing dosage of the catalyst, shortening reaction time, reducing addition quantity of formic acid, and reducing influence on the catalytic performance of other metal ions and the water content in a reaction system, and environment-friendly in production process. In addition, the prepared epoxy aliphatic ester is high in epoxide value, and the largest epoxide value can be over 4.6.

Description

technical field [0001] The invention relates to an epoxy fatty acid ester biological lubricating oil and a preparation method thereof. The method uses a vegetable oil fatty acid ester as a raw material and a metal ion-loaded cation exchange resin as a catalyst to prepare an epoxy fatty acid ester biological lubricating oil base oil . Background technique [0002] The development and application of ion exchange resin catalysts has made great progress, and many specific-purpose resin catalysts have been commercialized. Different types of cation exchange resins are based on their pore size and the ability to provide dissociated H + Different capacities have different catalytic activities. In the case that the exchange volume is basically the same, the pore size is the main factor affecting the catalyst activity. Gel-type resins have no true internal pores and are therefore less reactive than macroporous resins. In the case of the same pore size, the greater the exchange cap...
