Abstract: 1,176,036. Cyclohexadiene dicarboxylic acids. BADISCHE ANILIN- & SODA-FABRIK A.G. 23 March, 1967 [24 March, 1966], No. 13721/67. Heading C2C. [Also in Division C7] 3,5 or 2,5-Cyclohexadiene-1,2 or 1,4-dicarboxylic acid is produced by electrochemical hydrogenation of o- and/or tere-phthalic acid in aqueous H 2 SO 4 at 70-100‹ C. with a current density of 1-40 amp./sq. dm. on a cathode of Cd, Sn, Bi, Tl, or an alloy of at least two of the metals Pb, Hg, Ag, Cd, Sn, Tl and Bi; the cathode metal or alloy may be amalgamated. The phthalic acid may be dispersed in a concentration of 2-8% in aqueous H 2 SO 4 of concentration 2-50% by weight. The hydrogenation cell may be a heated or cooled doublewalled tube provided with a cylindrical cathode on or as its inner wall surrounding a cylindrical porous clay diaphragm and a water-cooled lead pipe anode; alternatively, the anode may be of Pb, Pt, PbO 2 , graphite or SiC. The catholyte may be continuously fed to the cell by a metering pump; withdrawn catholyte may be returned to the cell after crystallizing out the product and adding phthalic acid. Aqueous H 2 SO 4 may form the anolyte.
