The Role of Solvent on the Kinetics and Mechanism of the Hydrolysis of Salicylidene Benzoyl Hydrazone [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 1988 The effect of various solvents on the kinetics and mechanism of the hydrolysis of Salicylidene Benzoyl hydrazone (SBH) has been studied at five different temperatures (17-45 C) using U.V. and visible spectrophotometry. In both protic and aprotic solvents,
