| Abstract：The experiment employed styrene as row materials, hydrogen peroxide as an oxidant, ammonium molybdate as a catalyst, tri-n-butultinoxy as a phase-transfer reagent, sodium sulfate as a kindling, and chloroform as solvent to synthesize styrene oxide. The catalytic oxidation was studied by changing the dosage of catalyst, transfer reagent, reaction time and so on.It is shown that under the optimal conditions of 25ml of styrene, 25ml of hydrogen peroxide, 25ml of chloroform, 0.9g of ammonium molybdate, 2.5... |
