摘要： A process for making propylene oxide from propylene is disclosed. Propylene, hydrogen, and oxygen are reacted in a slurry comprising a catalyst and a solvent to produce a gaseous product stream and a liquid product stream. The gaseous product stream is contacted with an absorbent to produce a gas effluent and a liquid effluent. The gas effluent is recycled to the reaction step.

摘要： This invention is a process for producing propylene oxide. The process comprises first contacting a titanium zeolite with a reaction feed comprising propylene, hydrogen peroxide, tertiary butyl alcohol, and water to produce a product stream comprising propylene, propylene oxide, propylene glycol, tertiary butyl alcohol, and water. The product stream is distilled to produce a first overhead stream comprising propylene and a first bottoms stream comprising propylene oxide, propylene glycol, tertiary butyl alcohol, and water. The first bottoms stream is distilled to produce a second overhead stream comprising propylene oxide and a second bottoms product stream comprising propylene glycol, tertiary butyl alcohol, and water. The second bottoms stream is distilled to produce a third overhead stream comprising an azeotrope of tertiary butyl alcohol and water and a third bottoms stream comprising propylene glycol and water.
