METHOD FOR TREATMENT AND SEPARATION OF DISPERSED MEDIA AND COLLOIDAL SOLUTIONS Russian patent published in 2005 - IPC

FIELD: chemical technology.

SUBSTANCE: method involves treatment with silicon-containing flocculating agent and the following separation of product formed. For realization of method silicon-organic compound is used as a flocculating agent of the general formula: wherein values of indices p = 1-6; k, l = 0-1; m = 0.05-0.5; n = 0.0-0.8; sum of indices k + l + m + n = 1; active groups: J means Li, Na, K, Cs, and chelating agents: M means J, R₆; G means Cl, Br, J; radical values: R₁, R₂, R₃ mean CH₃, C₂H₅, C₃H₇, C₄H₉, CH₅, O[SiO₂]_qOJ wherein q = 1-9; R₄, R₅ mean CH₃, C₂H₅, C₃H₇, C₄H₉, C₆H₅, C₃H₅, C₃H₄F₃, C₃H₄Cl₃, C₃H₈N; R₆, R₇, R₈ means hydrogen atom (H), CH₃, C₂H₅, C₃H₇. Except for, for purifying sugar-containing solutions treatment with a flocculating agent is carried out in the presence of CaO expediently. Method provides simplifying and enhancing the effectiveness of the treatment process, reducing temperature and time of process. Invention is designated for purifying dispersed media and colloidal solutions and can be used for treatment of vegetable, mineral and synthetic oils, for cleansing sugar solutions, preparing and treatment of sewages and also in all manufactures wherein purifying solutions from dispersed and colloidal particle is required.

EFFECT: improved method for treatment.
