Reactions for formation of alkyl(aryl)chlorosilanes by direct synthesis

Conclusions

• 1. The direct participation of surface SiCl_n compounds in the formation of methylchlorosilanes was confirmed experimentally.

• 2. The partial chlorination products of silicon on the surface of the contact mass are centers for the activation of CH₃C1, on which its decomposition and the formation of methyltrichlorosilane take place in the thermal direct synthesis process (without a copper catalyst).

• 3. It was experimentally shown that the formation of methyltrichlorosilane in the thermal direct synthesis process is accompanied by a regeneration of surface compounds of the SiCl_n type, i.e., the synthesis process bears a chain character.
