Reaction Steps
To a mechanically stirred solution of commercial grade styrene (10.0 mol), commercial grade urea (26.6 mol), laboratory grade sodium bicarbonate (3.7 mol) and manganese sulphate (0.01 mol) in 2.50 L of water at 15° C. is added commercial grade 50% aqueous hydrogen peroxide (22.0 mol) slowly over a period of 5 hours. After 5.5 hours a separating funnel separated the organic layer of the reaction mixture. The crude styrene oxide was distilled to yield styrene oxide. The conversion to epoxide is 99% with selectivity 95%.
