Abstract

Elimination of para-substituted phenoxides from 4-(para-substituted-phenoxy)-2- oxobutanoic acids in aqueous solution is catalyzed by imidazole, morpholine, diethanolamine, and N, N-dimethylethanolamine. The dependence of the pseudo-first-order rate constant on amine concentration is nonlinear, with an initial line of large slope at low amine concentration which changes to a line of smaller slope at high amine concentration. ...
