DEFINITION

Classification: 524/284

Carboxylic acid or derivative and wherein the derivative is other than a metal salt DNRM:

(under subclass 81) Subject matter wherein the organic designated nonreactant material is a carboxylic acid or its derivative which is other than a metal salt.

(1) Note. See the Class 520 Glossary for the definition of a "carboxylic acid or derivative".

(2) Note. A carboxylic acid derivative for purposes of this subclass is limited to carboxylic acid esters, carboxylic acid linear anhydrides, carboxylic acid halides, and nonmetal salts of a carboxylic acid.

(3) Note. For purposes of this subclass, a metal salt of a carboxylic acid includes a metal salt having an organic substituent directly attached to the metal atom, e.g., R-O-Pb-O--R, and therefore such compound is excluded herefrom, see in particular subclass 330 for such a compound when the R of the RO group is aryl.

381, for the metal salts of hydroxy carboxylic acids, which are excluded from this subclass and its indents.

394, for sodium stearate.
