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

chlorofluorocarbon Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and p ...

with the formula HClC=C(H)CF₃. 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 refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated ...

in air conditioners. The compound exists as E- and Z-isomers. 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.
