This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a). As an alternative to chlorofluorocarbons, it has an ozone depletion potential of zero, a lower global warming potential (120) and a shorter atmospheric lifetime (1.4 years). It has recently been approved for use in automobile applications as an alternative to R-134a. ==Production== 1,1-Difluoroethane is produced by the mercury-catalyzed addition of hydrogen fluoride to acetylene: :HCCH + 2 HF → CH3CHF2 The intermediate in this process is vinyl fluoride, the monomeric precursor to polyvinyl fluoride. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1,1-Difluoroethane」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
