Thus this method could be applied to monitor the process of producing dinitrogen pentoxide by electrochemical oxidation of dinitrogen tetroxide in nitric acid. The results from the two-step titration method of redox titration combined with acidity titration were well consistent with that from the method of redox titration combined with NMR.
氧化还原和酸度两步滴定与氧化还原滴定结合核磁共振光谱法的分析结果表明，两种方法的分析结果吻合良好，精确度良好，两种方法都可用于N_2O_4-N_2O_5-HNO_3体系各组分的全浓度分析。

In order to determine the saturated vapor pressure of colloid ed dinitrogen tetroxide,and find out its change rule with the various temperature,a testing equipment of determining satuated vapor pressure of colloid ed dinitrogen tetroxide was designed and constructed according to the principle of static testing.
为了测定胶体四氧化二氮的饱和蒸气压，找出其在不同温度条件下的变化规律，采用静态法测试原理，自行设计建立了四氧化二氮胶体饱和蒸气压的测试装置，测得了常压下液体和胶体四氧化二氮的饱和蒸气压数据，结果表明，四氧化二氮体系成胶后比成胶前的饱和蒸气压略有降低，且温度越高其差值越大。

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。
