摘要

To compare the intramolecular assistance of ester hydrolysis with the intermolecular process, the hydrolysis of 0.075 M 0-methyloxime of DKP in the presence of 0.075 M acetone oxime at pH 7.5 (0.2 M phosphate) was studied. After 2143 h no ester hydrolysis was detected, although about 16% of the acetone oxime had hydrolyzed. Since about 5% ester hydrolysis could have been detected, the effective molaritys of the oxime hydroxyl ...
