Title: Process of producing ª‡-chloroglutaric acid
IPC: C07C29/124
Filed: 1962-08-14
Abstract: a -Chloroglutaric acid is produced by the following reaction scheme: <FORM:1007326/C2/1> The hydrolysis is carried out by heating the tetrachloropentane with an aqueous alkaline solution, or by heating with an alkali metal salt of an aliphatic carboxylic acid and hydrolysing the resulting ester.  The oxidation may be performed using any oxidizing agent known to oxidize alcohols to acids.  The dehydrochlorination is carried out by heating at between 90 DEG  and 160 DEG  C. under anhydrous conditions in the presence of a Friedel-Crafts catalyst.  The chlorine addition is done by mixing the compound with sulphuric, phosphoric, acetic or formic acid and passing chlorine through the mixture at a temperature below 20 DEG C. and pouring the reaction mass into water.  The Friedel-Crafts catalyst may be aluminium chloride, ferric chloride, tin tetrachloride, boron trifluoride, zinc chloride or bismuth chloride.
