标题:Synthesis of low-fluoride organic compounds
发明人：BRAUN MAX; EICHER JOHANNES; JANSSENS FRANCINE; EICHHOLZ KERSTIN; PALSHERM STEFAN
权利人:SOLVAY FLUOR & DERIVATE
摘要:Organic compounds, e.g. fluorinated organic compounds such as fluorinated carboxylic acids or fluorinated carboxylic acid chlorides, may contain small amounts of carboxylic acid fluorides, hydrogen fluoride or hydrolyzable fluoride, which during the preparation of derivatives of the fluorinated organic compounds, for example by esterification, may yield corrosive fluorides or hydrogen fluoride. The invention is a method for the synthesis and/or purification of preferably fluorinated organic compounds such as carboxylic acids, carboxylic acid chlorides and derivatives such as esters thereof, starting from corresponding carboxylic acid chlorides containing acid fluorides or hydrolyzable fluoride, and alcohols under the catalytic action of 'onium' salts of carboxylic acids, to obtain products which have a low fluoride content. Alternatively, an inorganic oxide adsorbent is utilized. The method is especially suitable for the synthesis of esters of trifluoroacetic acid, chlorodifluoroacetic acid, trifluoroacetoacetic acid and/or difluoroacetoacetic acid.

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 .

标题 :Hydrogenation of halogen-containing carboxylic anhydrides
发明人：NOVOTNY MIROSLAV
权利人:ALLIED CHEM
摘要:A process is described for the heterogeneous hydrogenation of haloalkyl, halocycloalkyl or haloaryl carboxylic anhydrides to the corresponding primary alcohols. In the haloalkyl or halocycloalkyl carboxylic anhydrides at least one halogen is in the alpha-position relative to the carboxylic anhydride grouping. The hydrogenation can be carried out in the liquid or vapor phase in the presence of a supported or unsupported catalyst comprising a member of the group consisting of rhodium, iridium, metal oxides thereof, or mixtures 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 anhydride 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 .

标 题 :Process for the preparation of perfluoroalkanols
发明人：CORDIER GEORGES; FERLUT JEAN-SERGE
权利人:RHONE POULENC SPEC CHIM
摘要:A process is disclosed for the preparation of perfluoroalkanols by reacting an ester of a perfluorinated acid in the liquid phase with hydrogen under a pressure of between about 1 and 300 bars in the presence of a catalyst based on at least one metal selected from nickel, cobalt, copper and the metals of the platinum group. The perfluoroalkanols are employed as synthesis intermediates in the pharmaceutical and plant-protection industries.
