硝胺炸药中水分测定

Determination of moisture content in nitramine explosive by an external-standard method

建立了测定硝胺炸药中水分的卡尔费休电量法。应用溶解能力极强的二甲基亚砜代替经典电解液中的部分试剂,制成改良电解液,提高了电解液对硝胺炸药的溶解能力;通过测定校正系数,采用外标法定量,解决了由于二甲基亚砜的引入致使测试结果偏低的问题。

An modified Karl-Fisher electrolyte method was established with dimethyl sulfoxide （DMSO）, a prasied alkahest, which had a strong ability of dissolution for many compounds, to replace classical eletrolyte for the determinatin of moisture in nitramine explosive, such as HMX and RDX. And the moisture content in nitramine explosive was quantified by an external-standard method to solve the problem of lower results by introducing DMSO.
