Title: Process for the preparation of dichloromaleic anhydride
Inventor: SIMONOV VADIM DMITRIEVICH
IPC: C07C51/305
Filed: 1976-08-05
Abstract: Dichloromaleic anhydride is prepared by oxidising hexachlorobutadiene in such a manner that the oxidation of hexachlorobutadiene is carried out with sulphuric anhydride at a temperature of 10-110 DEG C in the presence of iodine or an iodine-containing compound which forms iodine ions under the conditions of the reaction medium. The end product is then removed from the reaction mixture. To remove dichloromaleic anhydride, the reaction mixture can be distilled, a fraction which distils over at a temperature of below 138 DEG C being removed. The remainder of the mixture is cooled to a temperature of 0 DEG C, whereupon the precipitated dichloromaleic anhydride crystals are filtered, washed and dried. The present process allows an improved yield of dichloromaleic anhydride to be obtained in a simplified process.
