| 中文摘要: |
| 研究了以环氧丙烷和二乙烯三胺为原料制备N-羟丙基二乙烯三胺的方法.二乙烯三胺与环氧丙烷、硫酸、水的摩尔比为1:0.6:1:4.5,在30～35 ℃反应6 h,反应混合物经过中和、过滤、常压蒸馏得到粗产物,然后减压蒸馏,收集160～164 ℃ /1.3 kPa馏分20～30 g,收率为36%～54%.并探讨了投料比、滴加环氧丙烷的速度、反应温度等因素对反应收率的影响. |
| 英文摘要: |
| [Bis(2-aminothyl)amino]-2-propanol was prepared using 1,2-epoxypropane and diethylene triamine as raw materials.The optimum conditions were below :diethylenetriamine:1,2-epoxypropane:sulfuric acid:water = 1∶0.6∶1∶4.5(mol proportion),reaction temperature is 30~35℃ and rection time is 6 hours,then neutralized,filtrated,distilled,[bis(2-aminothyl) amino]-2-propanol was finally obtained through decompression distillation under 160~164 ℃/1.3 kPa.The velocity of the reaction was also investigated. |
