DEFINITION

Classification: 502/118

And a third component C (i.e., an additive other then a saturated hydrocarbon or an aromatic hydrocarbon free of aliphatic or cycloaliphatic unsaturation):

(under subclass 103) Catalyst composition which contains an added substance not provided for specifically by subclass 103 other than a saturated compound of carbon and hydrogen only, or other than a benzene ring containing compound containing no other unsaturation and containing only carbon and hydrogen.

(1) Note. Exemplary additives include olefins, cycloalkenes, alkeneylaromatics, dihdro naphthlene, substituted hydrocarbons and inorganic compounds etc. The composition may include an alkyl, cycloalkyl or aromatic compound in addition to the unsaturated compound but these latter do not alone qualify as additives for this subclass.
