Ammonium tetramythyl hydroxide is an organic base that is widely used in industrial scientific research. In China is mainly used as silicone products, such as silicone oil, silicone rubber, silicone resin and other synthesis of the main catalyst, although the dosage is not large, but for the yield and quality of products have a great impact. In foreign countries are mainly used in polyester polymers, textiles, plastic products, food, leather, wood processing, electroplating, microorganisms and so on. Ammonium tetramethyl hydroxide is now entering cutting-edge technologies, such as the printing of circuit boards and the manufacturing of microscopes, as anisotropic corrosive agent for the cleaning agent of integrated circuit boards and the Si-SiO2 interface in semiconductor microprocessing technologies. With the development of science and technology, the demand for this type of chemical reagent is increasing day by day, and the quality and quantity of ammonium tetramethamphetamine are put forward higher requirements. The principle of electrolysis is to prepare ammonium tetramethyl hydroxide in the anode chamber of the electrolytic cell, under the action of electric field force, the chlorine ions in the solution migrate in the direction of the anode until they discharge on the anode and extract chlorine gas. At the same time, due to the selective pervasivity of the ion membrane, chlorine ions can not spread through the ion exchange membrane, only the tetraamide ions can choose to pass through and enter the cathode chamber, and rich in it. The water molecules in the cathode chamber of the electrolytic cell are broken down into hydrogen and hydrogen-oxygen ions on the cathode. The latter happens to bind to ammonium tetraamide ions transported from the anode chamber into ammonium tetramythyl hydroxide. With the increase of electricity consumption and the increasing concentration of ammonium tetramyl hydroxide, the expected crude concentration was finally reached.
