| 摘 要： | 采用大分子反应法,将疏水性单体l-溴代十二烷(BD)接枝到羟乙基纤维素(HEC)上,对羟乙基纤维素进行疏水改性,制备了疏水改性羟乙基纤维素(HMHEC)。研究了离子液体种类、反应温度、羟乙基纤维素浓度和BD用量对HMHEC性能的影响。最佳合成条件为:HEC浓度为3%(质量分数),溶解时间1 h,溶解温度100℃,反应时间2 h,反应温度80℃,BD用量为2 mL。在1-烯丙基-2-甲基-咪唑氯盐体系中合成的HMHEC性能好于在1-丁基-2-甲基咪唑氯盐中合成的HMHEC。

| Abstract: | Hydrophobically modified hydroxyethyl cellulose (HMHEC) was prepared by macromolecule reaction.Hydroxyethyl cellulose was modified by grafting the hydrophobic monomer bromododecane (BD) on the hydroxyethyl cellulose (HEC).The influences of the type of ionic liquid,the reaction temperature,the concentration of hydroxyethyl and the dosage of BD on the performance of HMHEC were studied.The optimum conditions were that the concentration of HEC was 3%,the dissolving time was 1 h,the dissolving temperature was 100℃,the reaction time was 2 h,the reaction temperature was 80℃ and the dosage of BD was 2 mL.And the performance of the HMHEC that synthetized in the 1-allylic-2-methyl-glyoxaline chloride system was better than that synthetized in the 1-butyl-2-methyl-glyoxaline chloride system. |
