Description

technical field

[0001] The invention relates to a method for preparing difluoro-chloroethane and its production equipment, in particular to a method for producing difluoro-chloroethane by photochlorination reaction of difluoroethane and chlorine under the action of ultraviolet light Methods. Background technique

[0002] Conventionally utilize difluoroethane under the action of ultraviolet light and chlorine generation photochlorination to produce the method for difluoro-chloroethane to have: 1, the external photochemical reaction method that light source shines into the reactor from the outside of the reactor, like this The reactor is required to have good light transmission and is usually made of glass and quartz glass. Therefore, the reaction equipment is less and is easily damaged during use. At the same time, during the reaction, chlorine gas and some products make the reactor wall form a colored layer. film, which affects the amount of light; 2. There is a light sourc...
