(4-Methylphenyl)trimethoxysilane - Introduction

Tolyltrimethylsilane is an organosilicon compound with the chemical formula C10H16Si, commonly abbreviated as MTMS. Its nature includes the following aspects:

1. Physical properties: tolyltrimethylsilane is a colorless to yellow liquid, soluble in organic solvents, such as alcohols, ethers and aromatics.

2. Chemical properties: tolyl trimethyl silane with alkyl and phenyl two types of reactivity. It reacts with moisture in the air to produce silanol and toluene, and reacts with acids and alkalis to produce esterification, addition and substitution reactions.

The main uses of toluene trimethyl silane include the following aspects:

1. As a silane coupling agent: Tolyltrimethylsilane can chemically react with inorganic surfaces to form chemical bonds, thereby improving the adhesion and interfacial strength between different materials. Therefore, it is often used in rubber, plastics, coatings, adhesives, sealing materials and other industries.

2. As a lubricant: due to the alkyl moiety on the molecular chain of toluene trimethyl silane, it has the properties of reducing friction coefficient and reducing surface tension, so it is often used as a lubricant, such as in metal cutting fluids, electronic device manufacturing and aerospace and other fields.

The production method of tolyltrimethylsilane is mainly obtained by reacting toluene and trimethylchlorosilane in the presence of a catalyst. The catalyst is often used ferric chloride, aluminum chloride, etc. The reaction conditions are generally carried out at room temperature.

Regarding the safety information of tolyltrimethylsilane, it has low toxicity, but the following safety precautions still need to be followed:

1. Avoid inhalation and skin contact: When using or handling tolyltrimethylsilane, take appropriate ventilation measures to avoid inhalation of its vapor or mist, and avoid direct skin contact, if contact should be immediately washed with soap and water.

2. Keep away from fire sources: Tolyltrimethylsilane is flammable, avoid contact with fire sources, and keep away from open flames and high temperatures during storage.

3. Storage precautions: When storing toluene trimethyl silane, avoid light and high temperature environment, and store in a sealed container to prevent volatilization and leakage.
