Abstract

<PICT:0496709/IV/1> Epichlorhydrin is produced by distilling aqueous dichlorhydrin and a basic substance such as an alkali or alkaline earth hydroxide or carbonate at such a speed that the distillate contains dichlorhydrin and water, separating from the condensate the epichlorhydrin layer and returning the aqueous dichlorhydrin layer to the reaction. The reaction mixture is heated in a still A and the vapour mixture rises through a column D to a vessel E and a cooler F, the condensate flowing to a decanting vessel H. The lower epichlorhydrin layer is withdrawn at J while the upper layer passes by an overflow K to the column D. In one of the examples, a pressure of 220 mm. is employed.
