SORBENT OF HYDROCARBONS AND LIPIDS AND METHODS OF OBTAINING IT Russian patent published in 2008 - IPC B01J20/22 

FIELD: chemistry.

SUBSTANCE: sorbent of hydrocarbons and lipids contains fine dispersed material on which surface silicone fragments of the general formula: , where: R:O; R_a CH₃, R_b:CH₃, H; R_c:OCH₃, CH₃, n ≤ 50 are fixed. The method of obtaining the sorbent lies in the fact that the particles of the fine dispersed material modify silicon with organic fluid from the group: solutions of hydride-silicone fluids in the nonpolar solvents, aqueous emulsions of hydride-silicone fluids by gradual loading and mixing of components in a reactor at the temperature of 20-500°C in 15-60 minutes with speed of rotation of the mixer providing a regime of turbulence, with the subsequent drying within 3-4 hours at the temperature of 150±25°C.

EFFECT: invention ensures a single-stage method with an increase in the hydrophobicity and the decrease of the time of binding of sorbent with the extracted substances.
