Basic Information and Parameters

Phenyltrichlorosilane, with the CAS number 98 - 13 - 5, is an important organosilicon compound. It has the chemical formula C₆H₅SiCl₃. The molecular weight of phenyltrichlorosilane is approximately 211.56 g/mol. It is a colorless to yellowish - clear liquid with a pungent odor. This product is produced in our factory with high - quality raw materials and advanced manufacturing processes, ensuring its reliable quality and a very competitive price.

The boiling point of phenyltrichlorosilane is around 201 - 205 °C, and its melting point is about - 57.7 °C. It has a relative density of approximately 1.322 g/mL at 25 °C. It is soluble in common organic solvents such as benzene, toluene, and ether but reacts vigorously with water, alcohols, and amines.

Uses of the Product

Phenyltrichlorosilane has a wide range of applications in different industries:

Silicone Resin Production: It is a key raw material for the synthesis of phenyl - containing silicone resins. These resins have excellent heat resistance, weather resistance, and electrical insulation properties. They are widely used in the coating industry for high - temperature paints, electrical insulation coatings, and outdoor protective coatings.

Silicone Rubber Modification: By adding phenyltrichlorosilane during the production of silicone rubber, the heat resistance, low - temperature flexibility, and radiation resistance of the silicone rubber can be improved. This modified silicone rubber is used in aerospace, automotive, and electronic industries.

Coupling Agent: Phenyltrichlorosilane can act as a coupling agent between inorganic materials (such as glass fibers, silica) and organic polymers. It improves the adhesion and compatibility between these two different types of materials, enhancing the mechanical properties of composite materials.

Usage of the Product

Handling Precautions: When handling phenyltrichlorosilane, proper personal protective equipment (PPE) should be worn, including chemical - resistant gloves, goggles, and a respirator. It should be stored in a cool, dry, and well - ventilated area, away from sources of ignition, water, and moisture.

Reaction Conditions: In chemical reactions, the reaction temperature, pressure, and reaction time need to be strictly controlled. For example, in the synthesis of silicone resin, the reaction usually occurs under reflux conditions in an inert atmosphere (such as nitrogen) to prevent side reactions.

Dosage Determination: The dosage of phenyltrichlorosilane depends on the specific application and the desired properties of the final product. In the modification of silicone rubber, the amount added is usually determined according to the required improvement in heat resistance and other properties, and it is necessary to conduct preliminary experiments to optimize the dosage.

Detailed Usage Case Studies

Case 1: High - Temperature Coating Production

A coating company wanted to develop a high - temperature coating for industrial ovens. They used phenyltrichlorosilane as a key raw material for synthesizing phenyl - containing silicone resin. First, they mixed phenyltrichlorosilane with dimethyldichlorosilane in a certain ratio in toluene solvent. The reaction was carried out under reflux at 120 - 130 °C for 4 - 5 hours in a nitrogen atmosphere. After the reaction, the solvent was removed, and the obtained silicone resin was formulated into a coating with other additives. The resulting coating could withstand temperatures up to 300 °C without significant degradation, and it also had excellent adhesion to metal substrates, which met the requirements of the industrial oven coating.

Case 2: Silicone Rubber for Aerospace Applications

An aerospace materials manufacturer needed a silicone rubber with high heat resistance and low - temperature flexibility. They added a certain amount of phenyltrichlorosilane during the preparation of silicone rubber. The phenyltrichlorosilane was first hydrolyzed and then condensed with the base silicone rubber polymer. After vulcanization, the modified silicone rubber showed improved heat resistance up to 250 °C and maintained good flexibility at - 50 °C. This silicone rubber was used in the sealing gaskets of aerospace equipment, ensuring reliable performance under extreme temperature conditions.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Emma Kung

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."

Lisa Phoenix
