DEFINITION

Classification: 516/151

The nitrogen is part of the cation of a salt formed with the organic compound containing sulfoxy* (e.g., triethanol amine

salt, quaternary amine salt):

(under subclass 148) Subject matter in which the nitrogen of the organic* sulfoxy* containing compound is a part of the cation of a salt formed with the organic* compound containing sulfoxy*, such as, triethanol amine salt, quaternary amine salt.

(1) Note. The anion of the salt does not have to be the sulfoxy* group of the organosulfoxy* compound.
