Purity determination of ammonium dinitramide |
| |
| Abstract: | A rapid and simple method to determine the purity of ADN was studied.The experiment was carried out with non aqueous potentiometric titration into MI and a quaternary ammonium salt was used as the titrant,while AN,the major impurity present in ADN,which tends to cause serious interference,was removed by MI.The standard deviation of the method is 0.001 9 and its coefficient of variation is 0.19%. |
