C8E3 - Introduction
n-Octyl-trioxyethylene(n-Octyltriethoxysilane) is an organosilicon compound with the chemical formula C14H32O3Si. It is a colorless liquid with unique chemical properties and application value.
Regarding the properties, n-Octyl-trioxyethylene has low viscosity and low surface tension, and is easily soluble in many organic solvents. It can be hydrolysed to silicon trihydroxide and ethanol at room temperature. In addition, it can be cross-linked by reaction of silicon-carbon bonds with other compounds or materials.
In terms of application, n-Octyl-trioxyethylene is widely used as a surface treatment agent and chemical intermediate. It can form dense and stable chemical bonds on the interface of inorganic and organic substances, thus providing good adhesion and wetting properties. It is often used to improve the bond strength and durability of materials such as coatings, printing inks, adhesives and plastics. In addition, it can also be used as a waterproof agent, an anti-pollution agent and an antibacterial agent for textiles, and a surface treatment agent for glass, metals and ceramics.
The method for preparing n-Octyl-trioxyethylene can be carried out by the reaction of octanal and trioxyethylsilane. This reaction is usually carried out in the presence of alumina and a trioxyethylsilane catalyst under appropriate temperature and pressure conditions. The preparation process may involve control of the organic solvent, reaction time and reaction conditions.
Regarding safety information, n-Octyl-trioxyethylene need to be stored in a sealed container and avoid contact with air. During use, necessary protective measures should be taken, such as wearing protective gloves and eyes, and ensuring good ventilation conditions. Avoid inhalation of vapors, contact with skin and eyes. When handling this compound, correct operating procedures should be followed and relevant safety regulations should be observed.
