摘要： A preparation method of 1-chloro-2,3,3-trifluoropropene is provided. As a new eco-friendly compound that makes up a heat transfer medium, the 1-chloro-2,3,3-trifluoropropene (HCFO-1233yd) has been valued in the field of industrial cleaning and explosion-proof due to it excellent performance of low global warming potential (GWP) and ozone depletion potential (ODP) values, but HCFO-1233yd has high preparation cost that limits its large-scale application. In the preparation method of the present disclosure, 1,1,2,3,3-pentachloropropane is fluorinated into 1,2-dichloro-3,3-difluoropropene under the catalysis of a chromium-containing solid catalyst. Under the catalysis with a chromium-based catalyst as a main catalyst, 1,2-dichloro-3,3-difluoropropene is fluorinated with a hydrogen fluoride (HF) gas phase to generate 1-chloro-2,3,3-trifluoropropene, which greatly reduces the production cost of 1-chloro-2,3,3-trifluoropropene, and involves a simple preparation process, high product selectivity, and high raw material conversion rate.
