COMPOSITION AND METHOD OF IMPROVING FORMATION OF CRYSTAL AGGLOMERATES FROM MOTHER SOLUTION Russian patent published in 2015 - IPC C01F7/02 C01F7/34 C01F7/46 C01B13/36 

FIELD: chemistry.

SUBSTANCE: present invention relates to a composition for improving formation of crystal agglomerates during crystallisation from a mother solution, which includes: one or a mixture of fatty acids, esters thereof, amides or precursors in amount of 0.1-30%, white kerosene in amount of 15.1-50% and water, wherein said components together form an emulsion. The present invention also relates to a method of improving formation and extraction of crystal agglomerates during crystallisation from a mother solution, which includes the following steps: (i) adding a crystal growth-modifying composition to the mother solution according to claim 1 in an amount which is effective for increasing the size of crystal agglomerates; (ii) distributing the crystal growth-modifying composition in the mother solution and (iii) depositing crystal agglomerates from the mother solution.

EFFECT: obtaining large aluminium hydroxide crystals.
