摘要
以N2O5为硝化剂,缩水甘油为原料,通过考察工艺条件对硝化过程的影响,研究了硝化甘油的绿色合成过程。实验结果表明,H-ZSM-5分子筛具有较好的催化性能;适宜的催化剂浓度为15g.L-1,N2O5/缩水甘油的摩尔比为3:1,反应温度为15℃,在此条件下反应4h,硝化甘油的选择性达100%,收率达91.1%.
The green synthesis of nitroglycerin from nitration of glycido] with dinitrogen pentoxide （N2O5 ） as the nitrating agent was studied by investigating the effects of different parameters on the nitration of glycidol. Results show that H-ZSM-5 has good catalytic activity,and the preferred catalyst concentration is 15 g·L^-1 ,and the molar ratio of dinitrogen pentoxide to glycidol is 3 ： 1 and the temperature is 15℃. After reaction for 4 h under the above conditions, the selectivity of 100% and yield of 91, 1% for nitroglycerin were obtained.
