Epoxide production process, (a) a step of feeding at least one aqueous alkali and at least one halo Hi to gave the reactive distillation column, wherein the reactive distillation column is supplied to the area, the upper region disposed above the supply zone, and said feeding zone comprising a bottom zone disposed below the feed stage; (B) at the same time the step of stripping from the reactive distillation column, (ⅰ) epoxy halo to form a de Hi reacting at least a portion of alkali and gave, and (ⅱ) a basic water and the epoxide from the aqueous residue; (C) recovering as an overhead distillate (overheads fraction) of water and the epoxide from the reactive distillation column; (D) separating the condensed fraction of the overhead to form an aqueous overheads fraction comprising the organic epoxy overhead oil and water containing de; And (e) the liquid delay per plate in the feed zone includes the step of maintaining in a residence time of 10 seconds or less.
