METHOD OF OBTAINING MICROCAPSULES OF HETEROCYCLIC COMPOUNDS OF TRIAZINE SERIES Russian patent published in 2014 - IPC A61K9/50 B01J13/02 B01J13/04 A61K31/53 A01N43/66 A01N43/707 

FIELD: chemistry.

SUBSTANCE: invention relates to field of microcapsulation of heterocyclic compounds of triazine series. Method of obtaining microcapsules of triazine series pesticides is characterised by the fact that 0.1 g of triazine series pesticide and 0.02 g of E472c preparation as emulsifying agent are added to 10 g of 5% water solution of polyvinyl alcohol (PVA) and obtained mixture is subjected to mixing. Reaction mixture components are dissolved until transparent solution is formed after which 5 ml of carbinol as the first precipitating agent and then 10 ml of isopropanol as the second precipitating agent are added slowly drop-by-drop. After that, obtained suspension of microcapsules is kept for 1 minute, filtered on filter, washed with propanol several times, dried, with method being realised at 25°C without special equipment.

EFFECT: simplification of the process of obtaining microcapsules and increase output by weight.
