3069-40-7 - Introduction
(Octyl)-trimethoxysilane (n-octyl trimethoxysilane) is an organosilicon compound. Its chemical formula is C11H26O3Si and its molecular weight is 242.41g/mol.
(Octyl)-trimethoxysilane is a colorless liquid with a pungent odor. It has a low boiling point and flash point and is soluble in a variety of organic solvents, such as alcohols and ethers.
(Octyl)-trimethoxysilane has good weather resistance and chemical stability, and can be used as a surface treatment agent, crosslinking agent and adhesive. In coatings and paints, it can provide resistance to water, dirt and oil. In addition, it is widely used in the functional modification of polymers, fibers and particulate materials to provide moisture resistance, high temperature resistance, adhesion and wetting properties.
The method of preparing (Octyl)-trimethoxysilane is mainly through the reaction of n-octyl silicon chloride and trimethanol. The reaction is usually carried out in an organic solvent such as toluene or dimethylformamide. The reaction conditions can be adjusted on a case-by-case basis, such as temperature, reaction time and molar ratio.
When using (Octyl)-trimethoxysilane, you need to pay attention to its irritation and flammability. Prolonged contact with skin and eyes should be avoided, appropriate protective equipment should be worn, and a well-ventilated working environment should be ensured. In addition, during storage and handling, contact with oxidants and acids should be avoided to avoid unsafe chemical reactions.
In general,(Octyl)-trimethoxysilane is an important organosilicon compound with a wide range of applications and potential in many industrial fields.
