专利号:US-4544450-A 优先权日:1980-07-15 标 题 :Electrochemical process for the synthesis of organic compounds 发明人:OBERRAUCH ERMANNO; EBERSON LENNARD 权利人:ANIC SPA 摘要:An electrochemical process is disclosed for the synthesis of organic compounds, said process having the unique characteristic that the element evolved at the anode is exploited by having it reacting with the product of electrolysis obtained at the cathode by the presence of an appropriate catalyst. The catalyst may be associated in the most convenient manner to the anode, or it can be the anode itself. The process opens the way to a number of synthesis reaction which may be carried out electrolytically instead of the conventional ways.

Then, 2,5-dimethyl benzyl chloride is introduced into a reactor with an acid binding agent and a solvent, the carbonylation and hydrolysis reaction is conducted in the presence of a catalyst to obtain 2,5-dimethylphenylacetic acid. The present process has new route, less synthesis steps, simple operation, lower cost, increased yield, and is friendly to the environment. Therefore, the method is suitable for industrial production.
