METHOD OF PREPARING PEROXIDATED NANOSIZED SILICAGEL Russian patent published in 2010 - IPC C01B15/14 B82B3/00 C01B33/14 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of organoelemental peroxides which are potential materials for synthesis of modified polymers. The method of preparing peroxidated nanosized silicagel involves reacting chlorinated nanosized silicagel with hydroperoxide in the presence of a base in an organic solvent at room temperature. The base used is ammonia and the hydroperoxide used is hydrogen peroxide, tertbutyl hydroperoxide, geminal bishydroperoxides from a family which includes 1,1-bishydroperoxy cyclopentane, 1,1-bishydroperoxycyclohexane or genimal bishydroperoxides with general formula:

where R₁ = lower alkyl, R₂=H or methyl, R₃=H or lower alkyl, R₄=H or lower alky.

EFFECT: invention simplifies the process of synthesis of peroxidated nanosized silicagel and improves its quality.
