植物油からバイオ潤滑油を得るプロセス及びバイオ潤滑油

Japanese Patent JP7340181

B2

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 Figure 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.
