METHOD OF PREPARING OLIGOMETHYL-GAMMA-TRIFLUOROPROPYLSILOXANES Russian patent published in 2006 - IPC C08G77/24 

Abstract RU 2268902 C1

FIELD: organosilicon compounds.

SUBSTANCE: oligomethyl-γ-trifluoropropylsiloxanes are obtained via water hydrolysis of (di-)triorganochlorosilanes or their mixtures followed by hydrolysis product rearrangement in presence of catalyst, hydrolysis composition, in particular, including multifunctional silicon derivatives selected from group including organotrichlorosilanes and tetraethoxysilane and hydrolysis being conducted in presence of calcium chloride at its concentration 20-25 wt % in triple mixture of water-calcium chloride-hydrogen chloride with 20-25 wt % HCl.

EFFECT: considerably reduced content of low-molecular compounds in product having variable structure and composition.
