Abstract
This specification discloses a process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane in which chlorination of 1,1,1-trifluoro-2-chloroethane is carried out in the presence of activated carbon by feeding chlorine and hydrogen into a reactor simultaneously or sequentially, thereby enhancing the selectivity to 1,1,1-trifluoro-2,2-dichloroethane without lowering the conversion of 1,1,1-trifluoro-2-chloroethane.
