A method of making a catalyst includes reacting a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. The water may include less than or equal to 1 weight percent dissolved molecular oxygen. The catalyst may be used for degrading fluorinated organic chemicals in aqueous media.
专利号:US-4273947-A 优先权日:1979-01-31 标 题:Hydrogenation of fluorine-containing carboxylic acids 发明人:NOVOTNY MIROSLAV 权利人:ALLIED CHEM 摘要:A process is described for the heterogeneous hydrogenation of fluorine-containing alkyl, cycloalkyl, and benzene carboxylic acids to the corresponding primary alcohols. The hydrogenation can be carried out in the liquid or vapor phase in the presence of a solid rhodium or iridium catalyst, employed as the metal, metallic oxide, or mixture thereof. In the liquid phase, the hydrogenation can be carried out batchwise under mild conditions of temperature and pressure, preferably at about 50°-150° C. and about 5-15 atmospheres, in an atmosphere containing hydrogen gas. A preferred embodiment is the hydrogenation of trifluoroacetic acid in the liquid phase to 2,2,2-trifluoroethanol, said alcohol being useful as an intermediate in the synthesis of the anesthetic, isoflurane, CF 3 CHClOCHF 2 .
