标 题 :Method for continuous synthesis of 4-ethoxy-1,1,1-trifluoro-3-buten-2-one

摘要:Disclosed is a method for the continuous synthesis of 4-ethoxy-1,1,1-trifluoro-3-buten-2-one. The continuous synthesis method comprises: continuously introducing a raw material comprising vinyl ethyl ether, triethylamine and trifluoroacetic anhydride into a continuous reactor for a reaction to obtain a product system containing 4-ethoxy-1,1,1-trifluoro-3-buten-2-one, and continuously extracting the product system to obtain 4-ethoxy-1,1,1-trifluoro-3-buten-2-one. By using the continuous process, the above-mentioned raw materials can all be conveniently and accurately introduced into the continuous reactor, and after the reaction is completed, continuous extraction is also used for a post-treatment. The whole process is rapid, simple and efficient, the efficiency of the whole synthesis process is greatly increased, product destruction loss is reduced, and hidden safety hazards during batch production are avoided. After scaling up, there is no amplification effect, and safety and a relatively high synthesis efficiency can still be maintained.

标题:Synthesis of low-fluoride organic compounds

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.

权利人:RHONE POULENC CHIMIE
摘要:The subject of the present invention is a new catalytic system and a process for the synthesis of acid halides, especially from haloforms. This process for halogenating by means of a haloform is characterized by the use of a metal chloride, advantageously trivalent, as a catalyst, the solubility of which in the reaction mixture is at least equal to one millimole, preferably 1/100 mole per liter, and the metal chloride also being at least half, advantageously two-thirds and preferably three-quarters in the dissolved state.
