METALLOSILOXANES AS CATALYSTS OF HYDROFORMULATION, CARBONYLATION AND HYDROGENATION PROCESSES OF ORGANOSILICON COMPOUNDS AND METHOD OF THEIR SYNTHESIS

摘要

FIELD: chemical technology, organosilicon compounds. SUBSTANCE: product: siloxane derivatives, in part, metallosiloxanes of the formula {[CH₃)₃SiO_0,5][SiO₂]}_nM where n = 8-12; M - Cr, Mo, W, Fe, Ni, Co, Mn, Re, Rh, Ir, Os, molecular mass = 1140-1900. Synthesis is carried out by interaction of trimethylsiloxylsylsesquioxane of the formula {[CH₃)₃SiO_0,5][SiO₂]}_n, n = 8-12, with metal carbonyl of the formula M_m[Co]_n where M - as indicated above; m = 1-4; l = 4, 5, 6, 8, 10, 12, in organic solvent at 100-180 C, under pressure from atmospheric one to 5-7 ati.
