FIELD: nanotechnology.
SUBSTANCE: chloral hydrate powder is added to a suspension of kappa-carrageenan in butanol and 0.01 g preparation E472c, used as a surfactant. Then 10 ml of methylene chloride is added, the resulting nanocapsule suspension is filtered off and dried. The mass ratio core: the shell in nanocapsules is 1:3 or 1:1.
EFFECT: acceleration and simplification of the process of obtaining nanocapsules of chloralhydrate, and also increasing their yield by mass.
