DEFINITION

Classification: 554/169

(under subclass 163) Processes wherein glycerol esters, i.e., glycerides, are treated, (e.g., by heat, with catalyst, etc.) to cause the rearrangement of the -C(=O)O- groups, resulting in a different ester or mixture of esters.

(1) Note. Glycerides, or glycerol esters, are depicted thusly, as illustrated, below, wherein R= the same or different fatty acid radical.
