摘　　要：用热重一差示扫描量热（TG-DSC）测试方法研究了溴代正丁基吡啶盐[bpy]Br的热稳定性，并通过实验研究了它在不同溶剂中的溶解性能．结果表明：溴代正丁基吡啶的液态温度范围在99．8～400．0℃，发生热分解的起始温度为237．8℃．溶解性实验结果表明溴代正丁基吡啶能溶于极性较大的溶剂，暴露在空气中时具有较强的吸水性．In this paper, we reported the thermostability of butyl-bromopyridium（[bpy]Br）by means of thermogravimetry-differential scanning calorimetry（TG-DSC） as well as its solubility in different solvents. Our results indicate that, the liquid temperature range of [bpy]Br is much broadened from 99.8 ℃ to 400.0 ℃ and the critical decomposition temperature of [bpy]Br is at 237.8 ℃. The solubility experiment not only ,shows that [bpy]Br can be easily dissolved in the polar solvents, but presents good water absorbability if being exposed directly to air.
