CLAIMS

We claim:

1. A process for the preparation of functionalized castor oil derivatives from epoxidized castor oil (ECO) via ring-opening and/or transesterification, wherein conversion percentage of epoxidized castor oil is in the range of 82 to 91% comprising the steps of: (i) mixing epoxidized castor oil with a reactant at room temperature in...

DESCRIPTION

FIELD OF THE INVENTION

Present invention relates to a processes for the preparation of functionalized castor oil derivatives (ring-opened glyceryl ricinoleates, epoxy alkyl ricinoleates and ring-opened alkyl ricinoleates) with tailorable physical properties from epoxidized castor oil as raw material using recyclable solid (acid/base) catalysts wherein functionalization could be achieved either at the fatty chain...
