1-Oxohydrocarbyl-substituted azacyclohexanes compositions used as acid catalyst.

摘要

This invention provides a process for the conversion of a reactant into a reaction product in the presence of an acid catalyst which comprises contacting said reactant with an acid catalyst comprising a compound represented by the general formula wherein X may represent sulfur, oxygen or nitrogen; a and b may be 0 or 1, c may be 0,1 or 2, except that when X is oxygen, a, b and c are O, when X is nitrogen c is 0 and only one of a or b is 1, and when X is sulfur a and b are 0; A is a branched or a straight chain, divalent aliphatic radical having from 0 to 2 double bonds; R' is selected from the group consisting of H, a lower alkyl group having from 1 to 4 carbon atoms, phenyl, lower alkyl or halogen substituted phenyl, acetamido, halogen, piperidinyl, lower alkyl or halogen substituted piperidinyl, carbalkoxy, carboxamide, and alkanoyl; and R is hydrogen or a lower alkyl group having from 1 to 4 carbon atoms, wherein R'' is H or halogen, and salts thereof, and Z is selected from the group consisting of anions of strong acids.
