18765-09-8 - Introduction
Trioctylsilane, chemical formula C8H19SiH3, is an organosilicon compound. The following is a description of the nature, use, formulation and safety information of Trioctylsilane:
Nature:
1. Appearance: colorless liquid.
2. Melting point and boiling point: melting point is -130 ° C, boiling point is 155 ° C.
3. Density: 0.78g/cm³.
4. Flash point: 27 ° C.
5. Solubility: Soluble in organic solvents, such as ethanol, ether, etc.
Use:
1. Trioctylsilane is commonly used as surfactant, surfactant and lubricant.
2. Because of its long alkyl chain, it has the characteristics of good impurity resistance, so it is often used to add synthetic lubricants, industrial lubricants and greases.
3. Trioctylsilane can also be used to improve the fluidity of certain polymers and improve the flexibility of certain plastics.
Preparation Method:
Trioctylsilane can be synthesized by hydrosilylation. In General, 1-octene can be subjected to an addition reaction with hydrogen in the presence of a strong base to give trioctylsilae.
Safety Information:
1. Trioctylsilane may be irritating to the skin and should be rinsed with plenty of water immediately after contact.
2. Avoid inhaling its vapor or mist, and use appropriate protective equipment, such as respirators and chemical protective clothing.
3. Trioctylsilane should avoid contact with strong oxidants and acids during storage and use to avoid dangerous reactions.
