1977 Abstr. Papers 173rd Meeting Amer. Chem. Soc. (Physical Chem.) 9 Should replacement of CFCl3 and CF2Cl2 become necessary, it is likely that hydrochlorofluorocarbons..will be used.
1989 Chicago Tribune (Nexis) 14 July 1 [The] substitute is a compound of two hydrochlorofluorocarbons—HCFC-123 and HCFC-141B. Each has a much shorter life than CFC-11.
1990 New Scientist 30 June 33/3 As for CFC substitutes, the hydrochlorofluorocarbons (HCFCs).., the most likely outcome is that they will be included in the protocol for the first time under a special resolution covering so-called ‘transitional ozone-depleting substances’.
1999 Chem. in Brit. Mar. 42/1 A typical sticky foam formulation is..20 per cent chlorinated hydrocarbon as a fire retardant..and 30 per cent hydrochlorofluorocarbon (HCFC) or chlorofluorocarbon (CFC) as the solvent and blowing agent.
