DEFINITION

Classification: 522/33

Specified rate-affecting material contains a ketone group -c- (CO)n -c-, the (CO)n not being part of a ring:

(under subclass 6) Subject matter wherein the specified rate-affecting material contains at least one keto group which is not part of a ring system.

(1) Note. See Class 520, Glossary, for a definition of the term "ketone". The type of ketone materials excluded from this subclass are, for instance, those where oxygen is solely double bonded to a carbon atom and which carbon atom is part of a carbocyclic ring, or any other ring system.

(2) Note. Included in this subclass are those compounds which may contain two or more ketone moieties and wherein one of the C=O groups is part of a part of a ring system and wherein at least one C=O group is not.
