dimethyl(octadecyl)silicon - Introduction
n-Octadecyldimethylsilane(n-Octadecyldimethylsilane) is an organosilicon compound. It has a molecular formula of C20H43Si and a molecular weight of 313.65g/mol.
n-Octadecyldimethylsilane is a colorless liquid with low volatility and low surface tension. It is insoluble in water, but soluble in organic solvents such as ether, toluene and chloroform.
n-Octadecyldimethylsilane are mainly used as surfactants, lubricants and anti-corrosion agents. It plays an important role in many chemical synthesis and industrial applications. It can be used as a surface treatment agent to form a protective film on the surface of glass, metal, fiber and ceramic to increase its water resistance and wear resistance. In addition, it can also be used as a lubricant to reduce friction and wear. In some special applications, n-Octadecyldimethylsilane can also be used for surface modification of electronic devices to improve their performance.
The production method of n-Octadecyldimethylsilane is usually obtained by a silylation reaction. A common method of preparation is the use of trichlorosilane and octadecanol in the presence of a catalyst to give n-Octadecyldimethylsilane. It is necessary to pay attention to safe operation during the preparation process to prevent the release of toxic gases and the occurrence of emergencies.
It should be noted that n-Octadecyldimethylsilane it is irritating to the skin and eyes, contact should be avoided and good ventilation should be maintained. When using, it should follow the safety operation guidelines and follow relevant regulations and standards to avoid harm. If ingested or inhaled, seek medical attention immediately.
