Process for the preparation of halogenide-free quaternary ammonium salts |
| abstract |
Process for the preparation of quaternary organic ammonium salts with organic carboxylate or sulfonate anions, whereby an aqueous solution containing alkali hydroxide and quaternary organic ammonium halides is mixed with a solution of organic carbon or sulfonic acids in a water-immiscible solvent. The quaternary ammonium salts can be obtained free from alkali halides by this process. Because of their corrosive effect, these salts interfere with the use of the quaternary ammonium compounds as flow accelerators in closed systems. |
