摘要
提出了二硝酰胺铵 (ADN )产品的杂质分离及纯度分析的实用方法。结果表明 ,MIBK不仅是分离ADN产品的杂质硝酸铵 (AN)的有效溶剂 ,而且是化学滴定ADN的良好介质。纯度分析的精密度好 ,变异系数不大于 0 .19% ,准确度高 ,本法与碱量法相比 ,两种方法测定结果的相对偏差不大于 0 .2 5 %。
A useful method to separate the impurities from the ammonium dinitramide(ADN) product and to determine the purity of the ADN product is put forward.The results show that MIBK not only is an effective solvent to separate the ammonium nitrate(AN)impurities,but also is a good medium to chemicaly titrate the ADN.Both precision and accuracy of the purity analysis are good,the coefficient of variation is not more than 0.19%,the relative deviation of the results to be determined with two methods is not more than 0.25%.
