    production methodprocess of Tetraethylammonium hydroxide liquid

    Tetraethylammonium hydroxide CAS 77-98-5 is prepared by electrolysis, the principle is that the aqueous solution of tetraethylammonium chloride in the anode chamber of electrolysis tank, under the action of electric field force, the chlorine ions in the solution migrate to the anode direction until they are discharged on the anode and precipitate chlorine gas. At the same time, due to the selective permeability of ionic membrane, chlorine ions can not diffuse through the ion exchange membrane, only tetraethylammonium ions can selectively permeate into the cathode chamber, and enriched in it. Water molecules in the cathode chamber of the electrolyzer are decomposed into hydrogen and hydroxide ions on the cathode. The latter happens to combine with the tetraethylammonium ion migrating from the anode chamber to form tetraethylammonium hydroxide. The concentration of tetraethylammonium hydroxide increases with the increase of energization, and finally reaches the expected crude concentration. The anode electrochemical reaction is: (C2H5)4NCl→(C2H5)4N++Clˉ2Clˉ-2e→Cl2↑ The cathode electrochemical reaction is: H2O→H++OHˉ(C2H5)4++OHˉ→(C2H5)4OH2H+2e→H2↑ Total reaction is: 2(C2H5)4NCl+2H2O→ 2(C2H5)4OH+H2↑+Cl2↑The hydrogen generated in the electrolysis method is vented, and the chlorine generated is absorbed with lye to generate sodium hypochlorite, which is the main raw material for bleaching powder. Therefore, this method to prepare Tetraethylammonium hydroxide liquid is simple, high purity and no environmental pollution.

    • 1. First dissolve tetraethylammonium chloride with methanol, then add the theoretical amount of potassium hydroxide-methanol solution, mix well, that is, potassium chloride precipitation:When the reaction is complete, let it stand, pressurized filtration, the obtained filtrate is added with water and distilled under reduced pressure, alcohol and water are removed, so that the content of tetraethylammonium hydroxide in the solution reaches 44%, and then it is dried in vacuum, and the obtained crystals are the finished products.
    • 2. Firstly, dissolve the tetraethylammonium iodide with water to make it into a solution of 15%, and then add the theoretical amount of silver oxide, heat it in a water bath and keep it warm so that the reaction is complete:Filter off the silver iodide, the resulting crystalline filtrate is Tetraethylammonium hydroxide Raw Materials.
