Preparation method: There are many preparation methods of tetramethylammonium hydroxide, generally using silver oxide method, through the reaction of tetramethylammonium chloride and silver oxide to produce. However, the process of preparing tetramethylammonium hydroxide by this method is complex, the price of silver oxide is expensive, and the obtained products contain high impurity ions, such as halogen ions, alkali metal ions, etc., when used for catalytic polymerization of silicone monomers, the characteristics of silicone products are seriously affected, and it can not meet the requirements of cleaning and corrosion in the electronic field. A new process of preparing tetramethylammonium hydroxide by electrolysis has been adopted abroad since the 1970s, and has gradually replaced the silver oxide process. The products obtained by electrolytic method have good quality and low cost, which can not only meet the needs of silicone production, but also enter the field of electronics industry.

Chemical properties: Colorless crystal (often containing three, five grade crystal water), easy moisture absorption, in the air can quickly absorb carbon dioxide, 130℃ decomposition into methanol and trimethylamine, usually using 10%, 25% water (or alcohol) solution and containing crystalline water compounds.

Uses: As silicone rubber, methyl silicone oil auxiliaries and polarographic analysis reagents. In silicone, as dimethyl silicone oil, phenyl methyl silicone oil, silicone diffusion pump oil, solvent-free silicone molding plastics, silicone rubber and other catalysts. In the aspect of analysis, as a polarographic reagent, in the product purification as a ash-free alkali to precipitate many metal elements, in the production of organic silicon wafer is often used as a brightening agent for computer silicon wafer surface, cleaning agent and touch etching agent. Tetramethylammonium hydroxide as a catalyst, its advantage is that after the reaction is heated up, it can be decomposed into gas and driven away without remaining in the product.
