METHOD OF PRODUCING ZINC OXIDE MICROCAPSULES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to microencapsulation, particularly to a method of producing zinc oxide microcapsules. The method is characterised by that the microcapsule shell used is carrageenan, wherein a weighed portion of zinc oxide in dimethylsulphoxide is mixed with a suspension of carrageenan in butanol in the presence of an E472c surfactant; ethanol is added to the obtained suspension as a precipitant; the obtained suspension is filtered and dried at room temperature.EFFECT: method provides a simple and faster process of producing zinc oxide microcapsules, reduces losses when producing microcapsules.3 ex
