Steps:

1.3; 2.3; 3.3; 4.3; 5.3; 6.3; 1.3; 2.3

S3: 850g γ-chloropropyltriethoxysilane is pumped into the metering tank for measurement, and then enters the ammoniation kettle, and then 120g of liquid ammonia is added to carry out amination reaction. After the reaction, the crude product of gamma aminopropyl triethoxysilane and the by-product ammonium chloride were obtained. The reaction time was 6 hours. After the reaction was completed, the reactor material was pressed into the stirring tank for stirring. After the compressor, go to the condenser, condensate and recycle it into the liquid ammonia recovery tank for recycling, and after the stirring, the material is pressed to the centrifuge for centrifugal separation, the centrifugal solid is the by-product ammonium chloride, and the centrifugal liquid is temporarily stored in the crude product tank, and then transferred to the distillation still. , control the temperature in the kettle for vacuum distillation, steam out the front distillate and the finished product respectively, the front distillate is returned to the ammoniated kettle for application, the finished product is received into the finished product tank, after the distillation is completed, the still liquid is sent to the high-boiling distillation kettle for vacuum distillation, and the finished product is received into the finished product tank, After distillation, the still liquid is put into the still liquid tank and sent to waste treatment.
