Uses | 2-methyl-3-chloropropene, also known as methallyl chloride, is used to synthesize the mite agent phenobylbutylbenzene, an intermediate chlorotert-butylbenzene, It can also be used to synthesize the intermediate furan of the insecticide carbofuran. this product is an important organic intermediate, which can be widely used in medicine, pesticide, perfume, synthetic materials and other fields. It is the main raw material for the synthesis of insecticides such as carbofuran and phenylbutyltin. Organic intermediates are the main raw materials for the synthesis of insecticides such as carbofuran and phenylbutyltin. Used as an intermediate for pesticides, plastics, medicines, etc. Used to synthesize acaricidal tin, sodium methallyl sulfonate, 3-chloro-2-methylpropylene oxide, etc. |
Production method | 2-methyl-3-chloropropene is prepared by the reaction of isobutylene and liquid chlorine. Isobutylene and liquid chlorine are measured separately after gasification, and then passed into the reactor according to the appropriate ratio. The reaction is strongly exothermic, and the reaction contact time must be strictly controlled, and the reaction is evenly mixed in an instant. After the reaction, the material enters the reaction evaporator, removes the reaction heat, and then enters the absorption condenser, absorbs hydrogen chloride into hydrochloric acid, and then is cooled and separated by oleic acid. Hydrochloric acid can be sold as a by-product, and the organic layer is fractionated to obtain 2-Methyl -3-chloropropene, the content can reach 95% ~ 98%. |
