  • PROCESS FOR PREPARING HSiCI3 BY CATALYTIC HYDRODEHALOGENATION OF SiCl4
    Publication number: 20090035205
    Abstract: The invention relates to a process for the catalytic hydrodehalogenation of SiCl4 to HSiCl3 in the presence of hydrogen, in which at least one metal or metal salt selected from among the elements of main group 2 of the Periodic Table of the Elements (PTE) is used as catalyst at a temperature in the range from 300 to 1 000° C. In particular, the catalyst is a metal or metal salt which forms stable metal chlorides under these conditions.
