Method of sulfate of birch wood xilane |
| abstract |
FIELD: chemistry. n SUBSTANCE: method for sulfating xylan birch wood with chlorosulfonic acid in an organic solvent is characterized in that the sulfation is carried out in 1,4-dioxane at a temperature of 20-40°C for 3-6 hours, and xylan sulfate is isolated after neutralisation of the reaction mass with a 3% aqueous solution of sodium hydroxide, followed by purification by dialysis. n EFFECT: effective way of sulphating xylan. n 1 tbl, 9 ex |
