利用复分解反应制备了硝酸铵 (AN)炸药示踪检测添加剂十二烷基苯磺酸铈 (CDBS)和硬酯酸铈 (CSA)。用元素分析、ICP AES和FT IR表征了CDBS和CSA。DSC和VST法研究结果表明 ,CDBS和CSA与AN是相容的。用SEM、ESCA和FT IR观察了CDBS和CSA与AN的相互作用 ,认为 :固体CDBS和CSA可以自发地分散在AN颗粒表面 ,形成一层憎水膜 ,从而有效地防止AN的吸湿、结块 ,这一过程以物理吸附为特征。
Ammonium nitrate (AN) explosives tracer detection additive CDBS and CSA were prepared by metathesis reaction. CDBS and CSA were characterized by elemental analysis, ICP AES and FT IR. The results of DSC and VST studies show that CDBS and CSA are compatible with AN. The interaction between CDBS and CSA with AN was observed by SEM, ESCA and FT IR. The results showed that solid CDBS and CSA could spontaneously disperse on the surface of AN particles to form a hydrophobic membrane, effectively preventing moisture absorption and agglomeration of AN This process is characterized by physical adsorption.
