Chlorotris(isobutyl)silane - Introduction
Triisobutylchlorosilane is an organosilicon compound with the chemical formula C4H9ClSi(CH3)2. The following is a description of the properties, uses, preparation and safety information of triisobutylchlorosilane:
Nature:
1. appearance: triisobutyl chlorosilane is a colorless to pale yellow liquid.
2. melting point:-41 ℃.
3. Boiling point: 92 ℃.
4. density: 0.84g/cm³.
5. Solubility: Soluble in many organic solvents, such as alcohols, ethers and hydrocarbons.
Use:
1. silane coupling agent: triisobutyl chlorosilane can be used as an important silane coupling agent to improve the adhesion and durability of organic-inorganic interface, and to improve the performance of coatings, glass fibers and plastics.
2. Treatment agent: It can also be used as a treatment agent for rubber and plastics to improve its heat resistance and weather resistance.
3. Preparation of other compounds: Triisobutylchlorosilane can also be used to prepare other organosilicon compounds, such as silane sealants and waterproofing agents.
Preparation Method:
Triisobutylchlorosilane is usually prepared by reacting triisobutylchlorosilanol with hydrogen chloride. The reaction is carried out at room temperature in an inert atmosphere.
Safety Information:
1. triisobutyl chlorosilane is flammable when it encounters fire source, and it should be kept away from open flame and high temperature.
2. After contact with skin and eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical help.
3. in the use of the process should use appropriate protective measures, such as wear protective glasses, wear chemical gloves and wear protective clothing.
4. storage should be sealed in a cool, dry place, and away from the fire and oxidant.
