Abstract:
The invention relates to a method for the production of epichlorohydrin, wherein a chloropropane-containing ally chloride in excess is reacted in a first reaction stage with hydrogen peroxide. The non-reacted ally chloride is separated and returned to the reaction, wherein part of the separated ally chloride is added to a second reaction stage and reacted with hydrogen peroxide, wherein the hydrogen peroxide quantity is selected in the second reaction stage such that the ally chloride is largely reacted. The chloropropanes are separated from the reaction mixture of the second reaction stage by means of distillation and removed from the process.
