| 摘 要： | 本文在研究1,6-脱水葡萄糖均聚的基础上,提出了一种用1,6-脱水葡萄糖对瓜尔胶进行绿色化改性的新方法,并通过核磁对瓜尔胶的葡萄糖接枝产物进行表征,发现随着1,6-脱水葡萄糖与瓜尔胶质量比的增加,产物的葡萄糖摩尔取代度逐渐增大,当1,6-脱水葡萄糖与瓜尔胶质量比为3:1时,共聚产物的摩尔取代度可达0.6.1,6-脱水葡...

| Abstract: | Naturally occurring polysaccharides,such as cellulose,dextran,chitin and galactomannan,are widely used as raw materials for bio-related applications.Therefore,many efforts have been made in chemical modification and preparation of carbohydrate polymers,such as etherification,esterification and oxidation,which are referred to as graft copolymerization.Usually,non-regenerative petroleum products have been widely used in almost all of these modification processes.However,the petroleum resources are increasingl... |
