FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing organosilicon liquids. Disclosed is a method of producing oligodimethyl-γ-trifluoropropylsiloxane fluid as result of catalytic regrouping of initial combination consisting of (wt%): hexamethyldisiloxane (15±3), depolymerisate (32±5) and 1,3,5-trimethyl-1,3,5-tris(3,3,3-trifluoropropyl) cyclotrisiloxane (balance), in presence of sulfocationite (polistyrenedivinylbenzol sulphonated copolymer) in amount of 5±2 % to whole mass of starting composition, with further distillation of low-boiling fractions from product of catalytic rearrangement.
EFFECT: technical result is faster chemical process of fluid production and low level of losses of end product compared to existing methods.
