Process for production of highly pure quaternary ammonium salt |
| abstract |
A process for preparing a highly pure quaternary ammonium salt comprising: n (1) adding a quaternary ammonium hydroxide salt or quaternary ammonium carbonate to a quaternary ammonium salt containing a protonic acid salt of a tertiary amine as an impurity and thereby neutralizing the tertiary amine protonic acid salt with the quaternary ammonium hydroxide salt or carbonate to convert the acid salt to a tertiary amine and water and to convert the quaternary ammonium hydroxide salt or carbonate to a quaternary ammonium salt at the same time, and n (2) removing the tertiary amine and water produced from the system. |
