The results indicated that CHCl3 was optimum reagent and the reaction temperature was better controlled at 10~15℃. Dinitrogen tetraoxide and nitric acidhad a detrimental effect on the yield and purity of 1,2-propanediol dinitrate. When the concentrations of dinitrogen tetroxide and nitric acid were below 1.00% and 5.53% respectively, these detrimental effects could be neglected. Under the optimum conditions, the yields and the purity of 1,2-propanediol dinitrate were 99.01% and 95.89%, respectively.
同时考察了反应溶剂、反应温度、N_2O_5中N_2O_4和HNO_3杂质对1，2-丙二醇二硝酸酯收率和纯度的影响，结果表明，适宜的溶剂是CHCl3；适宜的反应温度为10～15℃；在适宜条件下，1，2-丙二醇二硝酸酯的收率和纯度可分别达到99.01%和95.89%；N_2O_4和HNO_3对产物的收率和纯度均有不利影响，但当N_2O_5中N_2O_4含量小于1.00%，HNO_3含量小于5.53%时，对产物收率和纯度的影响不大。
