DEFINITION

Classification: 8/115.56

Organic chemical reactant:

(under subclass 115.54) Subject matter wherein the chemical treating agent is an organic compound.

(1) Note. An organic compound is defined as one which has carbon therein and which is further characterized by the presence in a molecule of (a) carbon-to-carbon bond, or (b) carbon-to-hydrogen or carbon-to-halogen bond, or (c) carbon-to-nitrogen bond, with proviso that hydrocyanic acid, cyanogen, isocyanic acid, cyanamide, cyanogen halides, isothiocyanic acid, and metal carbides are excluded as being organic compounds.
