ENZYMATIC PROCESS FOR THE SYNTHESIS OF ESTOLIDES

摘要

The present invention relates to a process for enzymatic synthesis of estolides by reacting stearic acid with methyl ricinoleate using an immobilized lipase as a catalyst, in solvent-free medium. The present process results in a product that is less hygroscopic, prevents the product from degrading, reduces the formation of secondary products which generate colour and odour in the lubricant, and allows the lipase to be recovered for subsequent reuse thereof.
