Patent ID: 11492567

Abstract:
The present invention describes a process for obtaining a biolubricant from vegetable oil, which comprises the steps of (a) esterification reaction of the product of vegetable oil hydrolysis using a branched aliphatic alcohol; (b) epoxidation reaction of the esters obtained in step (a); and (c) nucleophilic substitution reaction of the epoxidated esters obtained in step (b) using a branched aliphatic alcohol. The present invention also describes a biolubricant obtained from the process. More specifically, a biolubricant is described that is produced from a ricinoleic fatty acid, whose formula is illustrated in FIG. 1 of the present invention, and where R1 is a hydroxyl or it is from the formula R3COO−, with R3 being an alkyl radical C1-C3, preferably a methyl radical; and R2 consists of a straight chain of hydrocarbons C4-C8 and a branched chain of hydrocarbons C1-C3.
