Application | 3-chloropropyltriethoxysilane is also called γ-chloropropyltriethoxysilane. 3-chloropropyltriethoxysilane is mainly used as an affinity coupling agent and tackifier in the market. The coupling agent can improve the interface between inorganic and organic substances, thereby greatly improving the properties of composite materials, such as physical properties, thermal properties, electrical properties, and optical properties. Silane coupling agent is a new type of plastic and rubber coupling agent, which can improve the wear resistance and aging resistance of tires, rubber plates, rubber hoses, rubber shoes and other products, and can reduce the amount of natural rubber, thereby reducing costs. |
preparation | (1) reaction process: uniformly fill the Ru-B/γ-Al2O3 catalyst with a load of 0.5% in a fixed bed, purge with nitrogen for 5min, and then raise the temperature to 115 ℃. Then 3-chloropropene and triethoxysilane are put into a stirred kettle according to a molar ratio of 1:1.5, the stirrer speed is 120r /min, the stirring time is 1h, and the mixed raw material liquid is obtained after mixing evenly. The mixed raw material liquid was passed through a fixed bed at a space velocity of 1.5 g/h/g Cat to obtain the reacted mixed product. (2) purification process: the mixed product after reaction is introduced into the distillation kettle, the distillation temperature is first raised to 45 ℃, then the distillation temperature is raised to 10 ℃ every 0.5h, until the distillation is finished at 0.5h after the temperature is raised to 75 ℃, and the pressure in the whole distillation process is -0.1MP. The distilled bottom material is introduced into the rectification tower, the bottom of the rectification tower is heated to 150 ℃ with a pressure of -0.1MP, and the materials at the top of the tower are collected to obtain the product. |
