摘要(Abstract)：
碱溶性羟乙基纤维素是纤维素的一种低醚化度的醚化产物,采用气固相的反应方法可以得到碱溶性良好、醚化度均一的羟乙基纤维素。研究了制备过程中影响产物碱溶性的相关因素,得到了制备碱溶性羟乙基纤维素的最佳实验条件。
Alkali-soluble hydroxyethyl cellulose(HEC),one of cellulose derivatives with lower etherification degree,could be made by the gas-solid reaction of cellulose and ethylene oxide.The effects of several reaction conditions on the alkali soluble HEC were investigated.Optimal experiment parameters for preparing HEC with better alkali-solubility were obtained.
