β-环糊精磺酰化及改性聚酰胺纤维研究

Study on the β-cyclodextrin sulfonylation and modified polyamide fibers

以对甲苯磺酰氯(p-TsCl)直接在β-环糊精的2号碳仲羟基处进行取代反应,合成了β-环糊精-2-磺酰酯,借助IR、UV以及溶解度的测定对产物进行了表征.探讨了β-环糊精-2-磺酰酯的合成条件及其对聚酰胺纤维的改性应用.结果表明:用-β环糊精-2-磺酰酯对聚酰胺纤维进行改性,将环糊精接到聚酰胺纤维上,可以改善聚酰胺纤维的吸水性、染色性等性能.

β-Toluenesulfonyl chloride （β-TsCI） took the substitution at the sec. hydroxyl of C-2 of β-cyclodextrin to synthesize β-cyclodextrin sulfonate （I）. The product was symbolized by the way of IR, UV and suly. detns. The synthetic conditions of β-cyclodextrin sulfonate and its application in polyamide fiber modification were probed. The results showed that the polyamide fibers modified with I for grafting cyclodextrin to the polyamide fibers could improve the hygroscopic and dyeing properties.
