摘要：
Oxidation kinetics of 2-phenylethanol by N-bromophthalimide (NBP) in aqueous acetic acid medium in presence of mercuric (II) acetate as a scavenger have been studied. In absence of mineral acids, the oxidation kinetics of 2-phenylethanol by NBP shows a first order dependence on NBP and fractional order on 2-phenylethanol. The variation of ionic strength. He(OAC)(2). H+ and phthalimide (reaction product) have insignificant effect on reaction rate. Activation parameters for the reaction have been evaluated from Arrhenius plot by studying the reaction at different temperatures. A mechanism involving transfer of hydride ion in rate determining step is suggested.
