Method for purifying quaternary ammonium hydroxides |
| abstract |
A process is described for reducing the latent halide content of a solution of quaternary ammonium hydroxide containing latent halide which comprises the steps of (A) providing an electrolytic cell comprising an anode and a cathode, (B) charging a solution containing at least one quaternary ammonium hydroxide which contains latent halide into said electrolytic cell, (C) passing a current through the electrolytic cell to lower the latent halide content in the solution, and (D) recovering the quaternary ammonium hydroxide solution from the electrolytic cell. A process also is described for reducing the latent and ionic halide content of quaternary ammonium hydroxides prepared from the corresponding halide. |
