ESTOLIDE DERIVATIVES PREPARED FROM TRIGLYCERIDES

A process to prepare an estolide derivative composition comprises reacting a triglyceride having an unsaturation level of less than 0.1 m Eq/g and an alcohol having from 2 to 22 carbon atoms, under conditions such that a product including an oligomerized ester having residual hydroxyl groups is form...

Zusammenfassung:A process to prepare an estolide derivative composition comprises reacting a triglyceride having an unsaturation level of less than 0.1 m Eq/g and an alcohol having from 2 to 22 carbon atoms, under conditions such that a product including an oligomerized ester having residual hydroxyl groups is formed; and reacting the product with a capping agent under conditions such that an estolide derivative composition is formed. The compositions may exhibit desirably low pour point, desirable viscosity and thermoxidative stability, and a high level of renewable carbons, making them suitable for use as biolubricants, process fluids, plasticizers, or starting materials for polyurethane polymers.
