【摘要】 本课题主要完成了硝酮类化合物N-氧自由基-N-十二烷基葡萄糖亚胺的合成和性能研究。采用两步法合成N-氧自由基-N-十二烷基葡萄糖亚胺。第一步,以葡萄糖和十二胺为原料,n(葡萄糖):n(十二胺)为1:1.3,反应温度为40℃,反应时间4 h,合成中间体N-十二烷基葡萄糖亚胺,通过测定葡萄糖的转化率对反应进行跟踪,葡萄糖转化率可达80 %。第二步反应,中间体在氧化剂H2O2和缓冲剂NaHCO3存在下,N2环境中在0～5℃下反应3h后转入55℃无水条件下反应20h合成了硝酮类化合物N-氧自由基-N-十二烷基葡萄糖亚胺,纯化后产率为60%。通过IR,元素分析和1HNMR对产品进行了结构表征。对合成的N-氧自由基-N-十二烷基葡萄糖亚胺进行了性能测定。其生物降解性、抗硬水性、增稠性、泡沫性的结果表明:N-氧自由基-N-十二烷基葡萄糖亚胺具有良好的生物降解性能;在抗硬水性实验中,N-氧自由基-N-十二烷基葡萄糖亚胺的表现出了较好的抗硬水性;在与AES和铵盐复配时,有一定的增稠性;发泡性良好,且泡沫稳定。将合成的N-氧自由基-N-十二烷基葡萄糖亚胺与多种酸复配后进行一系列的性能测定:表面张力、乳化力、保湿力。测定结果显示:N-氧自由基-N-十二烷基葡萄糖亚胺复配体系具有较好的降低表面张力的能力和乳化能力,并具有一定的保湿能力。更多还原

【Abstract】 The synthesis and properties of oxidated N-dodecyl glucosimine nitrone were studied in this thesis.Oxidated N-dodecyl glucosimine nitrone was synthesized for two steps .In the first step, the intermediate N-dodecyl glucosimine was prepared,using glucose and dodecamine and the molar ration of sugar to amine was 1:1.3,at 40℃for 4 hours.The reaction was controlled by determinating the transformation rate of glucose,which was 80%.In the second step, the intermediate was reacted with oxidizing agent H2O2 and buffering agent NaHCO3.The reaction temperature should be controlled between 0~5℃for 3 hours,then controlled bellow 55℃for 20 hours in the anhydrous condition.All the time the reaction was protected by N2.The yeild of oxidated N-dodecyl glucosimine nitrone after purification was 60%.The structures of target products was characterized with IR,1HNMR and elementary analysis.The properties of Oxidated N-dodecyl glucosimine nitrone were also studied.The results of its biodegradability,capability of resistance against hard water, thickening and bubble showed that its biodegradability was very good, the capability of resistance against hard water was ideal, it has a certain degree of thickening, foaming sound and foam stability when it was compounding with the AES and ammonium.Oxidated N-dodecyl glucosimine nitrone was mixed with acidic solutions and the properties in decreasing surface tension, emulsification and moisturing were studied.The results showed that oxidated N-dodecyl glucosimine nitrone mixture did well in decreasing surface tension and emulsification ,as well as moisturing.更多还原
