PROCESS FOR PRODUCING EPOXIDES
A process for producing epoxides, the process including: (a) feeding at least one aqueous alkali and at least one halohydrin to a reactive distillation column; (b) concurrently in the reactive distillation column: (i) reacting at least a portion of the halohydrin with the alkali to form an epoxide;...

Zusammenfassung: | A process for producing epoxides, the process including: (a) feeding at least one aqueous alkali and at least one halohydrin to a reactive distillation column; (b) concurrently in the reactive distillation column: (i) reacting at least a portion of the halohydrin with the alkali to form an epoxide; and (ii) stripping water and the epoxide from a basic aqueous residue; (c) recovering the water and the epoxide from the reactive distillation column as an overheads fraction; and, (d) condensing and phase separating the overheads fraction at a temperature of 50° C. or less to form an organic overheads fraction including the epoxide and an aqueous overheads fraction including water. |
