| 摘 要： | 为了改变褐藻酸丙二酯的溶解性,本文以氢碘酸为催化剂,将褐藻酸丙二酯与乙酐反应,制备了乙酰褐藻酸丙二酯。生成物不溶于水,可溶于多种中等极性的有机溶剂。本文用IR,~1H-NMR,HGPC对其进行了表征,并对反应条件对产率的影响进行了探讨。

| Abstract: | Propylene glycol alginate (PGA) and acetic annydride were reacted with hydroiodic acid as catalyst to prepare acetyl propylene glycol alginate in order to improve the solubility of propylene glycol alginate. The product was soluble in a lot of organic solvents with medium polarity, but insoluble in water. It was characterized by IR, 1H-NMR, HGPC. The influences of reactive conditions on the yield were investigated. |
