DEFINITION

Classification: 204/157.87

Carboxylic acid or derivative product:

(under subclass 157.6) Subject matter wherein the organic product which is the result of a wave energy process is a carboxylic acid or derivative.

(1) Note. A carboxylic acid for purposes of this subclass denotes:

A compound containing the structure A. --OH

A carboxylic acid derivative for this subclass is limited to ester, nonhetero anhydride, salt, and acyl halide.

A carboxylic acid anhydride denotes:

A compound containing the acyclic structure

B. --O-

A carboxylic acid ester denotes: A compound containing the structure

C. --O-C

wherein the carbon atom single bonded to the oxygen atom of the

--O- group is not double bonded to oxygen, selenium, or tellurium.

An acid hacioe denotes:

A compound containing the structure

D. --hal

The salt of a carboxylic acid denotes:

A compound containing the structure E. --

wherein X is a metal
