Description

The reaction of phenyl glycidyl ether (PGE) with benzoic acid (BA) catalyzed by tertiary amines and quarternary ammonium salts has been studied. The reaction catalyzed by quarternary ammonium salts is in goed agreement with second-order kinetics, according to<BR>-d[PGE]/dt=-d[BA]/dt=k, [PGE], [Cat. ]<BR>The tertiary amine catalyzed reaction, especially at the beginning ef the reaction, proceeds at a slewer rate than the reaction in the presence of quaternary ammonium salts. ln the reaction of PGE with BA in the prescnce of tertiary amines, catalyst amines react with PGE to form quarternary ammonium carboxylate salts, which is the actual catalyst in this reaction. The strtcture of the alkyl groups of amines has a large influence on the catalytic activity. ln the case of quarternary ammonium catalyst, the structure of alkyl groups does no affect the catalytic activity, but the type ef aniori associated with quarternary salt is very important.
