DEFINITION

Classification: 508/315

Carboxylic acid ester subsequently formed from alcohol or acid of the organic oxidate:

(under subclass 312) Compositions which contain a carboxylic acid ester subsequently formed from an alcohol or acid that is part of the organic oxidate of indeterminate composition.

(1) Note. This subclass does not provide for carboxylic acid esters of known structure, per se; such are classified as components in subclass 459 and its indents.

(2) Note. This subclass provides for components wherein an organic oxidate of indeterminate composition is made to undergo esterification (of either alcohol or carboxylic acid) to yield (1) a mixture, still of indeterminate composition, containing a carboxylic acid ester, or (2) a carboxylic acid ester of indeterminate composition.
