Endodiol Use and Manufacturing

Methods of Manufacturing

There are two methods for synthesizing endosulfanol: direct method and indirect method. In my country, the direct method is mostly used, which is prepared by the reaction of hexachlorocyclopentadiene and butenediol. Put the hexachlorocyclopentadiene and the solvent into the reactor, stir and heat to the reaction temperature, add butenediol dropwise, after the dropwise addition, keep the reaction temperature and continue to stir the reaction for 10h, after cooling, the endosulfanol crystallize After filtration and solvent washing, endosulfanol is obtained.

Uses

Endosulfanol is an intermediate of the organochlorine pesticide endosulfan.
