Introduction
Ethylphenyldichlorosilane is an organosilicon compound. It is a colorless liquid with a pungent odor at room temperature. It is a flammable liquid that burns when exposed to an open flame, high temperatures, or oxidizing agents.
Ethylphenyldichlorosilane is mainly used as an intermediate in the synthesis of silicones. It is one of the important raw materials for silicone compounds, which can be used to prepare silicone polymers, silicone lubricants, silicone sealants, silicone finishes, etc. It can also be used as a waterproofing treatment, coating interface modifier and ink additive, among others.
The preparation method of ethylphenyldichlorosilane can be obtained by the reaction of benzyl wood silane with thionyl chloride. Benzyl silane and thionyl chloride are first reacted at appropriate temperatures, and then hydrolyzed to obtain ethylphenyl dichlorosilane.
It is an irritant that can be irritating in contact with the skin, eyes, and respiratory tract, and should be properly protected by wearing protective eyewear, gloves, and masks. In addition, it is a flammable liquid, so it should be kept away from open flames and high-temperature sources, and used in a well-ventilated place. If inhaled or ingested, seek medical attention immediately.
