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: method of obtaining microcapsules of triazine series pesticides is characterised by the following: 0.1 g of triazine series pesticide and 0.02 g of E472c preparation as emulsifier are added to 10 g of 5% water solution of polyvinyl alcohol (PVA), and obtained mixture is subjected to mixing. After dissolution of reaction mixture components and formation of transparent solution 15 ml of isopropanol are very slowly drop-by-drop poured in, and obtained suspension of microcapsules is stayed for 1 minute, filtered on filter, washed several times with isopropanol and dried. Method is realised at 25°C without special equipment.

EFFECT: simplification of the process of obtaining microcapsules and increased output by mass.
