| titleOfInvention | Method for tandem production of trichloroethylene and tetrachloroethylene through two-stage reaction |
| abstract | The present invention discloses a method for tandem production of trichloroethylene and tetrachloroethylene through a two-stage reaction. The method comprises that a first-stage hydrogen chloride oxidation reaction is performed to prepare chlorine gas, the mixed gas after the reaction enters the second stage, and the mixed gas and dichloroethane are subjected to an oxychlorination reaction to produce trichloroethylene and tetrachloroethylene. The method specifically comprises: a first-stage reaction, wherein hydrogen chloride and oxygen are introduced into a fixed bed reactor or fluidized bed reactor to perform a hydrogen chloride oxidation reaction so as to prepare chlorine gas; and a second-stage reaction, wherein the mixed gas after the first-stage reaction and vaporized dichloroethane are introduced into the fluidized bed reactor, and the dichloroethane is subjected to an oxychlorination reaction to produce trichloroethylene and tetrachloroethylene. According to the present invention, with the process, the concurrent introduction of dichloroethane and high concentration oxygen into the same reactor is avoided, such that the dichloroethane raw material, the generated polychlorinated alkanes and the generated polychlorinated olefins directly contact the high concentration oxygen to carry out the deep oxidation reaction so as to generate COX, such that the yields of trichloroethylene and tetrachloroethylene, and the total yield of the organic chlorine products are improved. |
