METHOD OF SPLITTING BY-PRODUCTS RESULTING FROM DIRECT SYNTHESIS OF ALKYLCHLOROSILANES Russian patent published in 2001 - IPC

Abstract RU 2167878 C2

FIELD: chemical industry. SUBSTANCE: described is method of splitting heavy by-products resulting from synthesis of alkylchlorosilanes by treatment with hydrochloric acid in the presence of catalyst system. Catalyst system comprises at least one metal phosphate, all disilanes, heavy direct synthesis by-products such as wherein x=0-3, y= 0- 3, x+y=3, z=0-3, t=0-3, w=0-2, w+u=2, are substantially splitted and amount of hydrodesilanes is significantly increased in the course of process. EFFECT: more efficient method. 20 cl, 26 ex, 8 tbl
