| 摘 要：合成了室溫熔鹽溴化丁基吡啶和氟硼酸根丁基吡啶 ,通過(guò)紅外光譜鑒定它們具有季銨鹽結構 ,采用數字電導率儀和交流阻抗方法分別測定了其電導率。將溴化丁基吡啶與醋酸鋰復合后 ,電導率隨鋰鹽含量的增加而逐漸下降 ,當摩爾比為 1∶3時(shí) ,室溫下電導率從 8.78×10 -4S/cm下降到 1.84×10 -4S/cm。 |

| Abstract：In this paper, 1 butyl pyridinium bromide(BPBr) and 1 butylpyridinium tetrafluoroborate(BPBF 4) were synthesized, Their chemical structure were determined and analysed by means of infrared spectroscopy and the result showed that they have the structure of quaternaries, The conductivity of BPBr and BPBF 4 were determined by digital conductivity instrument and Ac impetance methods. The conductivity of the complex of BPBr and LiAc decreased when the content of LiAc increased. The conductivity of complex(BP... |
