对甲苯三甲基硅烷 - Introduction
Trimethyl-p-tolylsilane is an organosilicon compound with the chemical formula C11H18Si. The following is a description of its nature, use, preparation and safety information:
Nature:
Trimethyl-p-tolylsilane is a colorless to light yellow liquid with a special smell. It has a low density, a melting point of -75°C and a boiling point of 174-176°C. It can be dissolved in some organic solvents, such as ether and methanol.
Use:
Trimethyl-p-tolylsilane are mainly used as reaction reagents in organic synthesis. It can be used as a silicon source for the synthesis of compounds with organosilicon functions, such as silicon heterocyclic compounds and organic molecules containing silicon functional groups. In addition, it can also be used for surface modification of catalysts to improve their stability and reactivity.
Preparation Method:
Trimethyl-p-tolylsilane are generally prepared by reacting silane with p-toluene. Specifically, a Trimethyl-p-tolylsilane can be obtained by a Grignard reaction between phenylsilyl hydrochloride and trimethylchlorosilane.
Safety Information:
The Trimethyl-p-tolylsilane is generally stable under normal operating conditions, but should avoid contact with fire and high temperature. It may cause irritation to the skin, eyes and respiratory tract, so you should wear protective equipment when using it. At the same time, during the operation should avoid inhalation of its vapor or solution, avoid contact with the skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical help if necessary. Keep the chemical out of the reach of children, keep it properly, and avoid contact with incompatible substances. When using or handling this chemical, follow all safety practices and ensure that the work area is well ventilated.
