| 摘 要： | 淀粉作为胶粘剂的基体树脂主要由含多个羟基的葡萄糖单元组成,可通过化学、物理或生物等方法深加工成性能优良、品种繁多的淀粉衍生物。以硫酸铜为催化剂、双氧水为氧化剂,制备氧化淀粉。采用单因素试验法粗选制备氧化淀粉的较佳工艺条件;然后以pH值、氧化剂和催化剂用量为试验因素,以氧化淀粉中羧基含量为考核指标,采用正交试验法进一步优选制备氧化淀粉的最佳工艺条件。结果表明:当反应温度为45℃、反应时间为2.5 h、pH值为7、氧化剂为20 mL和催化剂为4 mL时,氧化淀粉中羧基含量(0.50%)相对最高。

| Abstract: | Starch,which was used as a matrix resin of adhesive,was mainly composed of polyhydric glucose unit.The starch derivants with good performance and multi-varieties could be obtained by chemical,physical or biological deep-processing methods.An oxidized starch with CuSO4 catalyst and H2O2 oxidant was prepared.The better process conditions of preparing oxidized starch were roughly selected by single-factor experiment method.Then with pH value,oxidant content and catalyst content as experiment factors,carboxyl c... |
