Abstract

Using the NMR method, the kinetics of decomposition of isopropylbenzene hydroperoxide catalyzed by dodecamolybdophosphoric acid has been invertigated in acetone at 22–50°C. The reaction is first order with respect to both the hydroperoxide and the catalyst, the activation energy is 14 kcal/mol. The data obtained are in agreement with the reaction mechanism suggested by Kharasch /1/.

Abstract

Методом ЯМР исследована кинетика разложения гидроперекиси изопропилбензола, катализированного фосфорномолибденовой гетерополикислотой, в среде ацетона при температуре 22–50°C. Установлено, что реакция имеет 1 порядок по гидроперекиси и 1 порядок по катализатору; энергия активации равна 14 ккал/моль. Полученные данные согласуются с механизмом реакции, предложенным Карашем (1).
