DEFINITION

Classification: 549/527

(under subclass 526) Processes wherein a naturally occurring unsaturated higher fatty acid having seven or more carbon atoms bonded to a carboxyl group, or an unsaturated derivative thereof, is epoxidized.

(1) Note. The term "derivative", as used herein, includes those chemical modifications which involve the conversion of the carboxyl group into a carbonylic derivative thereof which on hydrolysis reverts to the carboxyl group, e.g., salts, amides, esters, acid halides, and acid anhydrides, etc.
