Paragraph 0032-0043, (2021/06/22)
The invention discloses a method for preparing 3,3,3-trichloro-1,1,1-trifluoropropane through gas-phase catalytic chlorination through gas-phase catalytic chlorination. The method comprises the following step: under the action of a catalyst, subjecting 3,3-dichloro-1,1,1-trifluoropropane and chlorine serving as raw materials to a gas-phase catalytic chlorination reaction in a catalyst bed layer, wherein the catalyst is a molecular sieve, and the molecular sieve is at least one selected from ZSM-5, 5A, MCM-41, a beta type molecular sieve and a Y type molecular sieve. The molecular sieve which is cheap and easy to obtain is used as the catalyst, the reaction is carried out under a gas phase condition, and the method has the advantages of high space time yield, simple process, safe operation, low production cost and the like.
