N-2-(2-PYRIDYL)ETHYLCHITOSAN AND SYNTHESIS METHOD THEREOF |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to organic compounds and specifically to novel N-2-(2-pyridyl)ethylchitosan and synthesis method thereof. The said compound is obtained by reacting chitosan with aqueous solution of 2-vinylpyridine in the presence of hydrochloric acid in molar ratio 2-vinylpyridine: chitosan: hydrochloric acid equal to (2-4):1:1.The reaction is carried out at room temperature until formation of a gel. The gel is then heated to 68-72C for 24-48 hours. The cooled reaction mass is treated with aqueous hydrochloric acid solution. Deposition and subsequent hot extraction with water-soluble alcohols or ketones and drying are carried out. ^ EFFECT: obtained novel N-2-(2-pyridyl)ethylchitosan has high sorption capacity. ^ 2 cl, 1 tbl, 4 ex |
