T-BUTYLTRIMETHOXYSILANE - Introduction
T-Butyltrimethoxysilane, the chemical formula is (CH3O)3SiC(CH3)3, which is an organosilicon compound. The following is the nature, use, preparation and safety information of the T-Butyltrimethoxysilane:
Nature:
1. Appearance: colorless liquid
2. Molecular Weight: 148.29g/mol
3. Melting Point: ≈-100 ° C
4. Boiling Point: 101-102 ° C
5. Density: 0.798 g/cm
6. Solubility: soluble in alcohol, ether and other organic solvents, slightly soluble in water
7. Stability: relatively stable, when encountering moisture and humidity in the air, it will slowly hydrolyze to produce methanol and dimethoxysilane
Use:
1. T-Butyltrimethoxysilane commonly used in organic synthesis of protecting group reagent, in the synthesis of compounds can protect the reactivity of some functional groups.
2. It can also be used as a solvent, as a catalyst carrier or reaction medium in some reactions.
Method:
T-Butyltrimethoxysilane can be prepared by the following steps:
1. First, the reaction of tert-butyl silicon chloride and chloro methanol to generate tert-butyl trichlorosilane.
2. The tert-butyl trichlorosilane is then reacted with methanol to generate tert-butyl trimethoxysilane.
Safety Information:
1. T-Butyltrimethoxysilane is irritating and corrosive to the skin, and skin contact should be avoided when in contact.
2. Inhalation or swallowing T-Butyltrimethoxysilane may cause irritation to the respiratory and digestive systems. Avoid inhalation or contact with food.
3. When using T-Butyltrimethoxysilane, avoid contact with oxidants to avoid dangerous reactions.
4. Waste should be handled in accordance with local regulations to avoid environmental pollution.
