【Abstract】 In this paper, the. hydrolytic reactions of amitraz in the buffer solution at different pH values are studied. The results show that the order of hydrolytic reaction is one and the energy of activation is calculated through determining decomposion% of amitraz and rate constant under different temperatures and pH envioment while at the same time find out the dependence of hydrolytic reactions on pH. The results father prove that the mechanism of hydrolysis of amitraz is a special acid and base catalyzed reaction. In addition, the possible reactions during the hydrolytic reactions and mechanism are theoretically investigated through analyzing quantitatively the hydrolytic products.更多还原
