摘要:
Finely divided copper powder suitable for the preparation of copper catalyst for the synthesis of methylchlorosilane is prepared by adding an aqueous copper salt solution to an aqueous suspension of iron powder. Copper salt solutions obtained as process residues from the synthesis of methylchlorosilane can be used in the process of this invention.
