DEFINITION

Classification: 516/174

The compound is a salt composed of an organic anion and a nitrogen-containing organic cation (e.g., triethanol amine salt of oleic acid):

(under subclass 161) Subject matter in which the organic* compound which contains nitrogen is a salt composed of an organic* anion and a nitrogen-containing organic* cation, such as, triethanol amine salt of oleic acid.

(1) Note. This definition excludes carbonic acid salts and ammonium salts.
