| Overview | organic hydrogen-containing trialkoxysilanes are one of the important intermediates in organosilicon chemistry and industry, its importance in the silicone industry is second only to organohalosilanes. The general chemical formula is HSi(OR)3, where R is typically a straight hydrocarbon of less than 4 carbon atoms. |
| Application | The Si-OC2H5 bond in triethoxysilane can be converted into polysiloxane by hydrolytic condensation, Si-H bond energy with a series of alkenes, alkyne monomers in the platinum catalyst catalyzed hydrosilylation reaction to obtain a variety of organosilicon coupling agents (Y(CH2)n Si X3), silicone-terminated cured ethers and polyacrylate sealants and adhesives and other products, and suitable for the preparation of many high-purity organosilicon compounds, such as modified silane sealants, anti-fog agents, water repellents, silane coupling agents (e. G., vinyl, epoxy, and methacryloxy derivatives) and coating materials. |
| Application | is an important raw material for the synthesis of silane coupling agent, can also be used in the manufacture of silicone oil, polysilanes and the like are used as optical fiber materials The silane hydrogenation reaction is carried out with an olefin in the presence of a platinum (Pt) catalyst. Used as a reducing agent. |
