Technological process of oxidizing propylene with hydrogen peroxide solution to produce epoxy propane continuously

The process comprises four steps including reaction, separation of epoxy propane from the reaction product, recovering propylene and methanol solvent, and regeneration and concentration of catalyst. In the reaction step, one reactor suitable for fine grain catalyst is used, and its discharge slurry...

Beschreibung
Zusammenfassung:	The process comprises four steps including reaction, separation of epoxy propane from the reaction product, recovering propylene and methanol solvent, and regeneration and concentration of catalyst. In the reaction step, one reactor suitable for fine grain catalyst is used, and its discharge slurry is fed to one evaporating and regenerating tower, where propylene and epoxy propane are evaparated completely while the catalyst is regenerated. The concentration of the catast is effected through two-stage dynamic rotary vane filtering. The present invention realizes the continuous oxidizing propylene with hydrogen peroxide solution to produce epoxy propane.
