Abstract

Diallyl ether dioxide is produced by dehydrohalogenating a diallyl ether dichlorhydrin in presence of an aqueous solution of p a strong base, preferably at 0-25 DEG C. The reaction mixture is extracted with a solvent such as carbon tetrachloride and the extract, after removal of solvent, distilled under reduced pressure. Hydroxides and carbonates of alkali or alkaline earth metals are suitable bases. In examples, diallyl ether dichlorhydrins are prepared by reacting the monochlorhydrin, obtained from epichlorhydrin and allyl alcohol, with hypochlorous acid, by reacting diallyl ether with hypochlorous acid or by treating glycerol b -monochlorhydrin with epichlorhydrin in presence of boron trifluoride in acetic acid at 100 DEG C. They are treated with aqueous caustic soda at 15 DEG C. or room temperature to yield the dioxide.
