METHOD OF OBTAINING SULPHATED DERIVATIVES OF ARABINOGALACTAN |
| 摘要 |
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.1 tbl, 12 ex |
