In-Situ Epoxidation of Castor Oil Using Heterogeneous Acidic Ion-Exchange Resin Catalyst (IR-120) for Bio-Lubricant Application

The present work reports the formulation of castor oil (CO) epoxide as a bio-lubricant basestock. The main objective of this study was to improve the physico-chemical properties and thermo-oxidative stability of CO via structural modification. Epoxidation reaction was carried out at 60°C for 10 h us...

Epoxidation reaction was carried out at 60°C for 10 h using heterogeneous acidic ion-exchange resin (IR-120) as a catalysts (15mass%), acetic acid (0.5 mol) as an oxygen carrier and hydrogen peroxide (1.5 mol) as an oxygen donor.
