| titleOfInvention | Method for preparing trifluorotrichloroethane |
| abstract | The invention discloses a method for preparing trifluorotrichloroethane (113a) by utilizing difluoromono chloroethane, wherein, difluoromono chloroethane, chlorine gas and hydrogen fluoride perform a gas phase catalytic reaction under the temperature ranging from 80 to 180 DEG C, so that trifluorotrichloroethane is obtained; the molar ratio of difluoromono chloroethane and hydrogen fluoride is shown that difluoromono chloroethane:hydrogen fluoride equals to 1:2.0 to 5.5; the molar ratio of difluoromono chloroethane and chlorine gas is shown that difluoromono chloroethane: chlorine gas equals to 1:3.0 to 6.0; in addition, the whole technological process of the method can obtain the trifluorotrichloroethane (113a) through difluoromono chloroethane in a direct one-stage method, so that the process that chloridization is performed firstly and fluorination is performed secondly can be avoided, and the raw material cost or the operation cost of the whole process production can be lowered greatly. |
