1,4,5,6,7,7-hexachloro-bicyclo[2.2.1]hept-5-ene-3-dimethanol - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | endosulfan is an intermediate of the organochlorine insecticide endosulfan. |
| production method | there are two methods for the synthesis of endosulfan alcohol: direct method and indirect method. in our country, direct method is mostly used, which is prepared by the reaction of hexachlorocyclopentadiene and butene diol. Put hexachlorocyclopentadiene and solvent into the reaction kettle, stir and heat to the reaction temperature, add butylene glycol dropwise, after the dropwise addition, continue to stir for 10h at the reaction temperature, precipitate endosulfan crystals after cooling, and obtain endosulfan after filtration and solvent washing. |
