METHOD OF OBTAINING MICROCAPSULES OF HETEROCYCLIC COMPOUNDS OF 1,2,4-TRIAZINE SERIES Russian patent published in 2015 - IPC A61K9/50 A61K31/395 B01J13/06 

FIELD: chemistry.

SUBSTANCE: in the process of obtaining microcapsules by a physical-chemical method of precipitation by means of a non-solvent, a heterocyclic compound is dissolved in DMSO, the obtained solution is transferred into a PVP water solution, the first precipitating agent - a mixture of acetic acid in acetone, containing octyl ether of acridonacetic acid (OeAAA) as SAS, is added, and after that, the second precipitating agent - a mixture of OeAAA in acetone is added, the obtained suspension is filtered, washed with acetone and dried.

EFFECT: realisation of the invention makes it possible to simplify the process of obtaining microcapsules and increase the output by weight.
