(1) Reaction process: a Ru-B / γ-Al2O3 catalyst with a loading of 1.5% was uniformly packed in a fixed bed, purged with nitrogen for 5 minutes, and then heated to 115 ° C. Then 3-chloropropene and triethoxysilane were put into the stirring kettle at a molar ratio of 1: 1.5, the rotation speed of the stirrer was 120 r / min, and the stirring time was 1 h. After mixing, the raw material liquid was obtained. The mixed raw material liquid was passed through a fixed bed at a space velocity of 1.5 g / h / g Cat to obtain a mixed product after the reaction.(2) Purification process: The mixed product after the reaction is passed into a distillation kettle, the temperature of the distillation is first raised to 45 ° C, and then the temperature is increased by 10 ° C every 0.5h, until the temperature is raised to 75 ° C and the distillation is completed in 0.5h. The whole distillation process The pressure was -0.1MP. The bottom material after the distillation was passed into a rectification tower, and the temperature of the rectification tower tower kettle was raised to 150 ° C. and the pressure was -0.1MP. The material at the top of the tower was collected to obtain a product.
