本文叙述了用反相高效液相色谱法(HPLC)对双芳—3火药的乙醚提取物中硝化甘油(NG)、三硝基甲苯(α—TNT),二硝基甲苯(2,4—DNT、2,6—DNT)。二号中定剂(C_2)及苯二甲酸二丁酯(DBP)的分离分析方法。用装有YQG—C_(16)H_(33)(G·X)(5μ)固定相的Φ4×150mm不锈钢柱为分离柱,以60%甲醇水溶液为流动相,对一硝基甲苯(P—MNT)为内标分析NG、α—TNT、2,4—DNT、2,6—DNT。以80%甲醇水溶液为流动相,1号中定剂(C_1)作内标分析C_2和DBP。分析结果表明完全能满足部颁火药分析标准的要求。对同一样品经五次测定,其散度系数分别为NG:0.95%、α—TNT;0.50%、2,6—DNT:4.85%、2,4—DNT:1.52%、C_2:1.04%、DBP:0.89%、NC_1 0.32%。
In this paper, the effects of nitroglycerin (NG), trinitrotoluene (α-TNT), dinitrotoluene (2,4- DNT, 2,6-DNT). Separation and analysis of C 2 and DBP. A Φ4 × 150mm stainless steel column with a stationary phase of YQG-C_ (16) H_ (33) (G · X) (5μ) was used as a separation column and a 60% aqueous methanol solution was used as the mobile phase. MNT) for internal standard analysis of NG, α-TNT, 2,4-DNT, 2,6-DNT. Using 80% aqueous methanol as mobile phase, C 1 and C 1 were used as internal standard to analyze C_2 and DBP. The result of the analysis shows that it fully meets the requirements of the Proponent’s gunpowder analysis standard. The divergence coefficients of the same sample were determined as follows: NG: 0.95%, α-TNT; 0.50%, 2,6-DNT: 4.85%, 2,4-DNT: 1.52%, C_2: 1.04% : 0.89%, NC_1 0.32%.
