Title:
PROCESS FOR PRODUCING EPOXIDES
Document Type and Number:
WIPO Patent Application WO/2010/014892
Kind Code:
A3
Abstract:
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.
