摘要： A process for producing epoxide, the process including contacting an organic phase including at least one halohydrin(s) with at least one aqueous phase including a base in a plug-flow mixer/reactor system to disperse the organic phase in the aqueous phase via a mixing device imparting a power-to-mass ratio of at least 0.2 W/kg to convert at least a portion of the at least one halohydrin to an epoxide.

摘要： 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.

摘要： 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, wherein the reactive distillation column includes a feed zone, a top zone disposed above the feed zone, and a bottom zone disposed below the feed zone; (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; (d) condensing and phase separating the overheads fraction to form an organic overheads fraction including the epoxide and an aqueous overheads fraction including water; and (e) maintaining a liquid holdup per plate in the feed zone at a residence time of 10 seconds or less.
