METHOD OF PURIFICATION OF SOLUTIONS CONTAINING DISPERSE AND COLLOID PARTICLES Russian patent published in 2008 - IPC C10G21/26 C10M175/02 B01D21/01 C02F1/56 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical technology of purification of disperse media and colloid solutions. The method of purification of solutions is claimed. It contains disperse and colloid particles, using superhighmolecular element-organic floculant or inter-polymer complexes based on it, general formula where m=1-9; Radicals: R₁=(CH₂)_nPol, where n=2-4; R₂ and R₃ are selected from H; CH₃; C₂H₅; C₃H₅; C₃H₇; C₄H₉; R₄ and R₅ are selected from CH₃; C₂H₅; C₃H₅; C₃H₇; C₄H₉; C₆H₅; OH; OM; M=Na; K; Cs; R₆=(CH₂)_k, O; where k=1-4; R₇=R₄; [NR₁R₂R₃]O; Pol=Organic polymer, for instance, polyacrilate. Invention can be used for purification of liquid vegetable, mineral and synthetic oils, purification of sugar-containing solutions, preparation and purification of sewage waters, as well as in all industries, where it is necessary to purify solutions from disperse and colloid components.

EFFECT: simplification and increase of effectiveness of the process of purification of disperse media and colloid solutions with reduction of power expenditure.
