[0080] Preparation of 3-Chloropropyltrichlorosilane

[0081] The equipment used for the preparation of chloropropyltrichlorosilane is mainly composed of educt storage, diaphragm pump, adjustment assembly, measurement assembly and metering assembly, a T-mixer, 2 series replaceable and equipped with packing (average diameter of 1.5mm stainless steel ball), a prereactor (diameter 5cm, length 40mm, stainless steel), a stainless steel capillary (diameter 1mm, length 50m), a constant temperature bath for prereactor and capillary temperature regulation, a pressure stabilization valve, a continuous N2 Operation of the stripping column, and piping required for input of educts and output of products, recycle and waste gases.

[0082] First at room temperature olefin (propenyl chloride) and platinum-catalyst [53 g hexachloroplatinic acid-hexahydrate in 1 L acetone] were metered in molar ratio olefin:Pt=200000:1, mixed, and In the mixer, it is mixed with trichlorosilane (TCS, Degussa Com...
