FIELD: chemistry.SUBSTANCE: invention relates to encapsulation, particularly a method of producing microcapsules of a mixture of Vetom 1.1 and Sel-Plex in a carrageenan envelope. According to the disclosed method, Vetom 1.1 and Sel-Plex, taken in weight ratio of 60:40, are dissolved in dimethyl sulphoxide or dimethyl formamide. The obtained mixture is dispersed in carrageenan solution in benzene in the presence of an E472c preparation while mixing at 1000 rps. The mixture of the preparations and carrageenan are taken in weight ratio of 1:1 to 1:5. Butanol and distilled water, taken in ratio of 5:1 vol/vol, are then added. The obtained suspension of microcapsules is filtered out and dried. The process of producing the microcapsules is carried out at 25°C for 20 minutes.EFFECT: invention simplifies and speeds up the process of producing microcapsules, reduces losses during production thereof (high mass output).6 ex, 10 dwg |
