Abstract:
1. A process for the preparation of an alkylene oxide and a stream of glycol ethers comprising: Reacting an alkylene with hydrogen peroxide or hydrogen and oxygen under conditions sufficient to produce a product stream comprising the desired alkylene oxide; Introducing the product stream into a distillation column to produce a refined product stream comprising from about 70 to about 95 weight percent alkylene oxide, about 1 to about 30 weight percent alkyl alcohol and about 0.1 to about 4.9 weight percent water; Reacting the refined product stream with a catalyst comprising a metal-ligand complex, an acid, a base, or a combination of any number of these to produce a reacted stream comprising less than 1 wt % alkyl alcohol; and Introducing the reacted stream into a second distillation column to provide a substantially pure stream of alkylene oxide and a stream of glycol ethers.
