Synthesis and classification of phenyl silicone oil The synthesis of phenyl silicone oil usually involves multiple steps such as hydrolysis reaction, condensation reaction, and polymerization adjustment reaction. Firstly, methylphenyldimethoxysilane and diphenyldiethoxysilane were co hydrolyzed with dimethyldimethoxysilane, followed by equilibrium condensation to synthesize phenyl silicone oil with different benzene mole fractions. In addition, specific types of phenyl silicone oil can be produced through polymerization reactions.

According to the different benzene content, phenyl silicone oil can be divided into several grades, including low phenyl silicone oil, medium phenyl silicone oil, high phenyl silicone oil, high phenyl low polymerization degree silicone oil, and cross-linked phenyl silicone oil. Each grade of phenyl silicone oil has its unique properties and application areas.

For example, low phenyl silicone oil is particularly suitable for applications that require high cold resistance, as its stability at low temperatures allows it to maintain good fluidity even at extremely low temperatures. Medium phenyl and high phenyl silicone oils are often used as heat treatment baths and high-temperature heating oils for metal products due to their excellent thermal stability and radiation resistance.

In addition, there are some special phenyl silicone oil products, such as high-temperature resistant phenyl silicone oil, vinyl terminated silicone oil, low viscosity high vacuum diffusion pump phenyl silicone oil, etc. These products are highly regarded for their unique performance and wide range of applications
