128388-53-4 - Introduction
3,5-Diphenyl-1-trimethylsilylbenzene (abbreviated as TMDSB) is an organosilicon compound. It has a molecular formula of C20H22Si and an average molecular weight of 294.48g/mol. The following is an introduction to some of its properties, uses, formulation and safety information:
Nature:
TMDSB is a colorless to light yellow liquid with a strong fragrance. It has good stability at room temperature and is not easy to volatilize. It is almost insoluble in water, but soluble in organic solvents such as benzene and toluene.
Use:
TMDSB is widely used in the field of organic synthesis, especially as a catalyst, reaction intermediate and polymerization initiator. It can catalyze a series of organic reactions, such as silylation, silylation, condensation and cyclization. In addition, it can also be used for the organic preparation of functional polymers and silicone polymers.
Preparation Method:
The synthesis of TMDSB is usually accomplished by the reaction of diphenylmethylsilyl chloride and trimethylphenylsilanol. First, diphenylmethylsilyl chloride and trimethylphenylsilanol are reacted in an organic solvent (such as toluene), and after several steps, TMDSB is obtained.
Safety Information:
TMDSB is generally safe under normal conditions of use. However, due to its low volatility, it is recommended to take appropriate ventilation measures during operation to avoid inhaling gases or vapors. In case of contact with skin and eyes, rinse immediately with plenty of water and seek the help of a professional doctor. At the same time, it needs to be stored in a cool, dry, well-ventilated place, and away from heat and fire sources. During use, please follow all relevant safety operation guidelines and regulations.
