| Abstract: | Thermal stability,equilibrium vapor pressure,and standard enthalpy of sublimation of 1-carboxymethyl-3-methylimidazolium chloride(Cl) are investigated using both non-isothermal and isothermal thermogravimetric analysis under high purity nitrogen.The non-isothermal TG curve shows that the onset and peak decomposition temperature are 547 and 570 K,respectively.However,the long-term isothermal TG studies reveal that the highest application temperature for Cl is 433 K.Moreover,the temperature dependence of equi... |
