Abstract:
(EN) The present invention provides a production method which has a high selectivity to HCFC-132 and in which handling is easier than in conventional methods because neither chlorine nor highly toxic carbon tetrachloride is used. Specifically, the present invention provides an HCFC-132 production method characterized by comprising a step in which a halogenated ethane represented by the general formula CFClX-CFClX (1) (wherein the X moieties are each independently Cl, Br, I, or H and at least either of the X moieties is Cl, Br, or I) is reduced in the presence of a reducing agent to yield 1,2-dichloro-1,2-difluoroethane (HCFC-132).
(FR) La présente invention concerne un procédé de production qui présente une sélectivité élevée vis-à-vis du HCFC-132 et dans lequel la manipulation est plus facile que dans les procédés classiques étant donné que ni le chlore ni le tétrachlorure de carbone hautement toxique n'est utilisé. La présente invention concerne particulièrement un procédé de production de HCFC-132 caractérisé en ce qu'il comprend une étape dans laquelle un éthane halogéné représenté par la formule générale CFClX-CFClX (1) (dans laquelle les fractions X sont chacune indépendamment Cl, Br, I, ou H et au moins l'une ou l'autre des fractions X est Cl, Br ou I) est réduit en présence d'un agent réducteur pour produire du 1,2-dichloro-1,2-difluoroéthane (HCFC-132).
(JA) 本発明は、塩素及び毒性の高い四塩化炭素を使用しない点で、従来法に比して取り扱いが容易であり、且つHCFC-132の選択率が高い製造方法を提供する。本発明は、具体的には、一般式(1):CFClX-CFClX(式中、Xは、各々独立してCl、Br、I又はHである。ただし、Xのうち少なくとも一つは、Cl、Br又はIである。)で表されるハロゲン化エタンを、還元剤の存在下で還元して1,2-ジクロロ-1,2-ジフルオロエタン(HCFC-132)を生成させる工程を含むことを特徴とする、HCFC-132の製造方法を提供する。
