First, fluoroalcohol and chlorosilane are used as raw materials. First take an appropriate amount of 3, 3, 4, 4, 5, 6, 6, 7, 7, 8, 8 - tridecafluorooctyl and put it in a clean reactor. Fully replace the air in the kettle with nitrogen to create an inert atmosphere. Add trichlorosilane slowly dropwise to the reactor, and add an appropriate amount of organic base as acid binding agent, such as triethylamine. Control the reaction temperature at 40 - 60 degrees Celsius and stir the reaction for 8 - 12 hours. After the reaction is completed, the unreacted raw materials and by-products are removed by vacuum distillation, and the fractions with a specific boiling point are collected to obtain the target product.

Second, fluoroolefins and silanes are used as raw materials. In an autoclave, add 3, 3, 4, 4, 5, 6, 7, 7, 8, 8-trifluorooctene and triethoxysilane, and add an appropriate amount of transition metal catalysts, such as platinum catalysts. Seal the reactor, fill it with nitrogen and pressurize it to 2-4 MPa, raise it to 80-120 degrees Celsius, and react for 6-10 hours. After the reaction is completed, it is cooled to room temperature, separated and purified by column chromatography, and rinsed with a suitable eluent to collect the eluent containing the target product, steam off the solvent, and obtain pure triethoxy (3, 3, 4, 4, 5, 5, 6, 7, 8, 8 - trifluorooctyl) silane.

During the preparation process, it is necessary to precisely control the reaction conditions and strictly implement the operating specifications to ensure the purity and yield of the product.

Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8-tridecafluorooctyl) What are the precautions for silane during use
