Catalyst for fluorination of 1,1-dichloro-1-fluoroethane and process for the preparation of 1,1,1-trifluoroethane using the same

摘要

A catalyst for fluorination of 1,1-dichloro-1-fluoroethane which is obtained by mixing chromic hydroxide and an aqueous solution of magnesium chloride, reacting the mixture with an aqueous solution of HF and then calcining the resulting product and a process for preparing 1,1,1,-trifluoroethane by reacting 1,1-dichloro-1-fluoroethane with HF in the presence of the above catalyst are provided.
