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 :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.

标题 :Processes for preparing pentafluoroethoxy- and pentafluoroethylthiobenzene drivatives
发明人：DESBOIS MICHEL; LANGLOIS BERNARD
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the preparation of (pentafluoroethoxy)- and (pentafluoroethylthio)benzene derivatives either from phenol, thiophenol or from halobenzene. A halobenzene is reacted with trifluoroethanol or a phenol or a thiophenol is reacted with a compound of the formula CF3-CH2-O-R'. The product is chlorinated and the chlorinated product is fluorinated in liquid hydrofluoric acid in the presence of a Lewis acid. The compounds obtained by the process of the present invention are used as synthesis intermediates in the phytosanitary, pharmaceutical and veterinary industries, and are used in lubricants.
