一类新型低熔点盐的合成与表征

Synthesis and Characterization of a Series of Low-Melting Salts

以N,N-二甲基吡啶和直链溴代烃为原料,在丙酮中合成一类新型的低熔点盐。采用元素分析,FT-IR,热重等对所合成的目标化合物进行了结构和性质研究。结果表明,化合物1～7展现了较高的热力学稳定性,其熔点和阳离子中的烷基链长之间没有呈现简单的单调关系。

A series of low- melting salts based on N, N -dialkylpyridinium were synthesized and characterized by EA, IR spectroscopy and TG analysis. These compounds show a hign thermodynamic stability. The melting and al- ky chain length of those compounds showed non - linear relationship.
