    摘要: A multiple liquid phase composition and process for preparing propylene oxide including a reaction mixture of: (a) propylene, (b) at least one peroxide compound, (c) at least one catalyst, such as a titanium silicalite-1 (TS-I) catalyst, and (d) and a predetermined amount of a solvent mixture; wherein the solvent mixture comprises at least (i) at least one alcohol, such as methanol, and (ii) at least one non-reactive co-solvent; wherein the solvents are mixed at a predetermined concentration; wherein the non-reactive co-solvent has a different boiling point than propylene oxide; and wherein the resulting propylene oxide product partitions into a high affinity solvent during the reaction. The process of the present invention advantageously produces a waste stream with little or no significant amount of sodium chloride (NaCl).
