Brit. /ˌhʌɪdrə(ʊ)ˌklɔːrəʊˈˌflʊərəʊˈˌkɑːb(ə)n/, /ˌhʌɪdrə(ʊ)ˌklɒrəˈˌflʊərəˈˌkɑːb(ə)n/, U.S. /ˈˌhaɪdroʊˌklɔroʊˈflɔroʊˌkɑrb(ə)n/, /ˈˌhaɪdroʊˌklɔroʊˈflʊroʊˌkɑrb(ə)n/[see also chloro- comb. form1, fluoro- comb. form.]
[‹ hydro- comb. form + chloro- comb. form2 + fluorocarbon n. Compare earlier hydrofluorocarbon n.]
Any of a class of partly chlorinated and fluorinated hydrocarbons, some of which are used as an alternative to CFCs in foam production, refrigeration, etc. Abbreviated HCFC.
| 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. |
