Abstract

The reactivity of .OH radicals toward stable molecules in acetonitrile has been studied using laser flash photolysis. .OH radicals have been generated by 260 nm photolysis of H2O2 and the rate of their disappearance was measured using N,N-dimethyl-p-nitrosoaniline as acceptor. It has been established that in acetonitrile .OH radicals manifest high reactivity towards ethylbenzene and its oxidation products (1-phenylethanol, 1-phenylethyl hydroperoxide, acetophenone). The corresponding rate coefficients were in the range 106-107 dm3 mol-1 s-1 and were lower than such coefficients observed in aqueous solutions.
