Abstract: The carbon-carbon double bond in the molecule of 1-chloro-3,3,3-trifluoropropylene (HCFO-
1233zd) gives it an extremely short life cycle in the atmosphere and an extremely low global warming
potential. In addition, HCFO-1233zd has the characteristics of low toxicity and uninflammability. As a
result, HCFO-1233zd has been identified as an environmentally friendly alternative to chlorofluorocarbons,
which is in the same class as hydrofluoroolefins in terms of environmental performance and belongs to the
fourth-generation product. The synthetic routes and application of HCFO-1233zd are reviewed. In terms of
the synthetic routes, the synthesis route of HCFO-1233zd(E) from 1,1,1,3,3-pentachloropropane (HCC-
240fa) by gas phase fluorine-chlorine exchange has easy access to raw materials, high conversion rate, high
selectivity and industrial value, while the synthesis route of HCFO-1233zd(Z) by gas phase isomerization
using HCFO-1233zd(E) as raw material has the advantages of long catalyst life, high target product
selectivity and easy to realize industrialization. In terms of application,HCFO-1233zd(E) is mainly used as
foaming agent and heat transfer fluid, while HCFO-1233zd(Z) is mainly used as cleaning agent. Finally, the
research priorities of HCFO-1233zd in the future are the development of high activity non-chromium
catalysts and the new application technologies.
