IN352939: Ricinoleic and dibasic acid based estolide esters useful as lubricant basestocks

Acces sibility Controls

A novel class of tetra and triesters are prepared by reacting ricinoleic acid methyl ester with dibasic acids (C6,8,io)- The carboxylic acid moiety present in triesters was esterified with different alcohols with varying chain length. All the products were characterized by *H NMR, 13CNMR, FT-IR, and ESI-MS analysis and evaluated for their physico-chemical properties like acid value, density and lubricant properties namely viscosity, viscosity index (V.I), pour point and oxidation stability by Differential Scanning Calorimeter. The products exhibited very low pour points (-48 to
