| titleOfInvention | A kind of method preparing expoxy propane |
| abstract | A kind of method that the invention provides preparing epoxypropane by epoxidation of propene, it includes making propylene, hydrogen peroxide initial ring oxidation reaction in the presence of organic solvent, quaternary ammonium salt phosphor-tungstic heteropoly acid catalyst and additive, before the method farther includes epoxidation reaction, after the steaming water pretreatment containing hydrogen peroxide solution system and epoxidation reaction, reactant mixture is carried out post processing, isolates propylene, expoxy propane, partial solvent and water.The method technique is simple, and system production concentration is high, and catalysts and solvents is easily recycled to be applied mechanically, and is suitable to industrial applications. |
