Solvent Effect on the Kinetics of the Basic Hydrolysis of Isatin

Autor: Hamed M. Abu El-Nader, M. N. H. Moussa

Publikováno v: Chemical and Pharmaceutical Bulletin. 44:1641-1646

The kinetics of the basic hydrolysis of isatin in the presence of ehanol and ethylene glycol has been investigated spectrophotometrically. The rate of the reaction decreases with increasing ethanol content and it passes through a minimum at about 30%
