METHOD FOR THE TREATMENT OF TECHNICALLY PURE HALOSILANES FROM ELEMENTS OF THE THIRD MAIN GROUP AND INSTALLATION FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for reducing the content in elements of the third main group of the periodic system, especially in boron-and/or aluminum-containing compounds of technically pure halosilanes for producing purified halosilanes, especially high-purity chlorosilanes and they are treated with triphenylmethylchloride and mechanical separation of settled complexes are carried out.
