Process for improving the purity of quaternary ammonium hydroxides by electrolysis |
| abstract |
A process for improving the purity of a composition comprising a quaternary ammonium hydroxide by electrolysis using cation selective membranes. The process is particularly suitable for improving the purity of an aqueous solution comprising tetramethylammonium hydroxide which has been used in the production of 4-aminodiphenylamine for a number of reaction cycles. |
