1-Chloro-3,3,3-trifluoropropene (HFO-1233zd) is the unsaturated

chlorofluorocarbon Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly Halogenation, halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F). They are produced as volatility (chemistry), volat ...

with the formula HClC=C(H)CF₃. The compound exists as E- (''cis-'') and Z- (''trans-'') isomers. The ''trans-'' isomer of this colorless gas is of interest as a more environmentally friendly (lower GWP; global warming potential)

refrigerant A refrigerant is a working fluid used in the cooling, heating, or reverse cooling/heating cycles of air conditioning systems and heat pumps, where they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are ...

in air conditioners. It is prepared by fluorination and dehydrohalogenation reactions starting with 1,1,1,3,3-pentachloropropane.Tung, Hseuh Sung; Ulrich, Kevin D.; Merkel, Daniel C.
