摘　　要：通过离子交换法,由BMIC(氯化—1—甲基—3—丁基咪唑)出发,首先合成了碱性离子液体中间体BMIOH,然后利用酸碱中和反应除水得到了新型的氨基酸离子液体BMIGlu(谷氨酸基—1甲基—3—丁基咪唑盐),并使用HWR一15型恒温微机热量计测定了这种离子液体的恒容燃烧能△C_E,进而得到了BMIGlu离子液体的标准摩尔燃烧△_CH_m~θ焓,并进一步计算得到其标准摩尔生成焓△fH_m~θ=-1891,71 kJ·mol^(-1)。估算方法简便易行,可以得到难以测得的热化学数据,并可用于其它离子液体的热化学研究中。An new ionic liquid BMIGlu （Glutamic-1- butyl -3- methylimidazole） was synthesized from the alkali intermediate BMIOH prepared by BMIC using neutralization and water remove. The molar combustion enthalpy of the BMIGlu ＇was determined using the oxygen--bomb calorimeter based on the energy of combustion. Its standard molar enthalpy of formation was calculated and obtained, △fHm^θ= -1891.71 kJ·mol^-1. The thermo chemical data which hard to determime can be obtained by this simple and convenient method and the method also can be used in other ionic liquid research.
