liquids (RTILs) and the others (ILs) melt well below the decomposition temperature of the salts, ca. 80 °C. Unlike the analogous amidinium carbamate RTILs, which are made by adding CO2 to amidine/amine mixtures and decompose near 50 °C, the amidinium dithiocarbamates do not revert to their amidine/amine mixtures when they are heated. The thermal, rheological, conductance, and spectroscopic properties
通过将一当量的CS 2添加到两个非离子分子(idine和胺)的等摩尔混合物中,就可以制备具有不同结构的二硫代氨基甲酸铵盐。用这种方法制得的许多盐是室温离子液体(RTIL),而其他盐(ILs)的熔融温度远低于盐的分解温度。80℃。与类似的氨基甲酸氨基甲酸铵RTIL不同,后者是通过添加CO 2制成的到am /胺混合物分解并在50°C附近分解时,二硫代氨基甲酸am铵在加热时不会还原为their /胺混合物。报告了总共50种IL和RTIL中代表性实例的热学,流变学,电导率和光谱学性质,比较了它们与它们的非离子相(以及与氨基甲酸氨基甲酸铵类似物)的比较,以及热分解途径对二硫代氨基甲酸铵进行了研究。
