| titleOfInvention | Process for partial electrolyte dehalogenation dichloro- and trichloro-acetic acids and electrolysis solution |
| abstract | Tri- and dichloroacetic acid is dehalogenated to monochloroacetic acid by electrolysis of aqueous solutions of these acids in divided electrolysis cells using carbon cathodes; the aqueous electrolysis solutions also contain one or more metal salts with a hydrogen overvoltage of at least 0.4 V (at a current density of at least 4000 A / m²) and special ammonium and / or phosphonium salts.n n n In this process, an extremely low evolution of hydrogen occurs at the cathode even at a very low concentration of the multiply chlorinated acetic acid, without the high selectivity of the electrolysis deteriorating during continuous operation. |
