SiCl4 cold hydrogenation catalyst

Thread Content

The copper(I) chloride produced by our company is used in the cold hydrogenation process to convert SiCl4 (abbreviated as STC), which is a by-product of the polysilicon production process, into SiHCl3 (abbreviated as TCS). The main reaction principle is as follows: Si + 2H2 + 3SiCl4 → 4SiHCl3 (main reaction); (1) SiCl4 + Si + 2H2 → 2SiH2Cl2 (side reaction); (2) 2SiHCl3 → SiCl4 + SiH2Cl2 (side reaction). The copper(I) chloride catalyst for cold hydrogenation produced by our company features stable quality and excellent performance, with a conversion rate of over 25%.
