DEFINITION

Classification: 522/44

Containing C-CO-C(R)(OR) wherein R is organic, e.g., diethyoxacetophenone, etc.:

(under subclass 33) Subject matter wherein the ketone compound contains the structure, below, wherein R is organic. For an example, see the structure following the one immediately below. [figure] [caption]etc.

(1) Note. Diethoxyacetophenone is considered proper for this subclass unless specifically identified as to where the ether linkages are connected and which, if specified, differ from that required by the definition of this subclass.
