ABSTRACT:
To prepare dichloromaleic anhydride, hexachlorobutadiene is subjected to oxidation with sulfur trioxide at a temperature ranging from 10 to 110.degree. C in the presence of iodine or an iodine-containing compound such as an alkali metal iodide, whereafter the desired product is separated from the reaction mass.
The method of the present invention makes it possible to increase the yield of dichloromaleic anhydride up to 96% by weight, whereas in the prior art methods it is 80% by weight at most; the reaction time in the method according to the present invention is reduced by about 10 times as compared to that of the prior art methods.
