METHOD OF OBTAINING SULPHATED DERIVATIVES OF ARABINOGALACTAN Russian patent published in 2015 - IPC C08B37/00 C07H5/10

Abstract RU 2546965 C1

FIELD: chemistry.

SUBSTANCE: method includes the interaction of arabinogalactan with a sulphating complex sulphaminic acid-urea in dimethylsulphoxide with continuous mixing and a temperature of 75-85°C for 2.0-3.0 hours. The product is extracted after the neutralisation of the reaction mixture by an ammonia water solution by sedimentation in ethyl alcohol with the following purification by dialysis.

EFFECT: method makes it possible to obtain a water-soluble product and increase the environmental friendliness and efficiency of the process with the application of a novel system of reagents.
