METHOD OF PRODUCING MICROCAPSULES OF HETEROCYCLIC COMPOUNDS OF TRIAZINE SERIES Russian patent published in 2015 - IPC A61K31/53 A61K47/32 A61K9/50 A61J3/07 B01J13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing metribuzin microcapsules. Said method is characterised by mixing aqueous polyvinyl alcohol solution with metribuzin and E472c, stirring the mixture until dissolution of components of the reaction mixture and then adding methyl carbinol as a first precipitant and isopropanol as a second precipitant, filtering the obtained microcapsule suspension, washing with isopropanol and drying.

EFFECT: invention provides a simple process of producing metribuzin microcapsules in a water-soluble polymer, and increases mass output.
