PROBLEM TO BE SOLVED: To provide a method for preparing 3,3,3-trifluoropropene (1243zf). SOLUTION: CCl 3 CH 2 CH 2 Cl (250 fb) is fluorinated in a first reactor using HF as a fluorinating agent to form a liquid phase CF 3 CH 2 CH 2 Cl (253 fb). ), And (b) dehydrohalogenating 253 fb in the presence of a catalyst in the second reactor to produce 1243 zf in the gas phase, 3,3. Method for preparing 3-trifluoropropene (1243zf). [Selection diagram] Fig. 1 |
