Tetramethylammonium hydroxide pentahydrate Usage
1. Silicone rubber, methyl silicone oil additives, and polarographic analysis reagents.
2. In organic silicon, dimethyl silicone oil, phenylmethyl silicone oil, silicone diffusion pump oil, solvent-free silicone moulding plastics, silicone rubber, and other catalysts.
3. In the aspect of analysis, as a polarographic reagent, ashless alkali is used to precipitate many metal elements in product purification.
4. In the production of organic silicon wafers, it is often used as a brightener, cleaner, and touch agent for computer silicon wafers.
5. As a catalyst, tetramethylammonium hydroxide has the advantage of heating up after the reaction, which can decompose it into gas and drive it away from the product.
