INCLUSION COMPLEX OF ELEMENTAL SULFUR WITH CYCLODEXTRIN Russian patent published in 2008 - IPC C08B37/16

Abstract RU 2321598 C1

FIELD: chemical technology.

SUBSTANCE: invention relates to the inclusion complex of cyclodextrins with elemental sulfur. Complex can be prepared using different homologues of cyclodextrins, for example, beta- and gamma-cyclodextrins and hydroxypropylated forms of gamma- and beta-cyclodextrins. Proposed complex can be used as a biologically active compound for medicinal, veterinary and agricultural designation. Invention provides the possibility for further preparing true solutions of elemental sulfur in water in the concentration up to 250-300 mg/l.

EFFECT: improved preparing method, valuable properties of complex.
