烟火剂型底排药中氯丁橡胶和松脂酸钙测定方法研究

烟火剂型底排药成分分析用甲苯-乙酸乙酯混合溶剂溶解氯丁橡胶、松脂酸钙和六次甲基四胺，通过蒸馏水萃取除去六次甲基四胺组分，盛装于烧杯中蒸干的氯丁橡胶、松脂酸钙再用乙酸乙酯溶解松脂酸钙转移分离，从而实现氯丁橡胶和松脂酸钙定量分离检测研究。产品检测应用表明，甲苯一乙酸乙酯混合溶剂对单质氯丁橡胶、松脂酸钙、六次甲基四胺回收率在98％以上。试验研究和实际产品检验中，氯丁橡胶、松脂酸钙硷测误差均在±1．5％内（相对误差小于10％）.该方法也可应用于类似混合炸药的成分分析。

Determination of Chloroprene Rubber, Calcium Resinate in Pyrotechnic Composition BB Pellet

In the analysis of pyrotechnic composition BB pellet,toluene ethyl acetate mixed solvent used for dissolving chloroprene rubber,calcium resinate and six methyl four amine was extracted by distilled water.After the compound being dried,the left chloroprene rubber,calcium resinate were dissolved by toluene–ethyl acetate mixed solvent,thereby the quantitative separation and detection of chloroprene rubber and calcium resinate were realized.Product detection application showed that the recoveries of toluene–ethyl acetate mixed solvent to chloroprene rubber,calcium resinate amd six methyl four amine were more than 98%.The detection error of chloroprene rubber,calcium resinate in experiment and actual production was within±1.5%(the relative error was less than 10%).This method also can be used in the similar mixed explosive composition.
