摘要：

The stoichiometric equilibrium constant, K prime , for the autosolvolysis reaction for the aluminum chloride-1-methyl-3-ethylimidazolium chloride ionic liquid was investigated as a function of temperature with a chloroaluminate concentration cell and aluminum electrodes. The values obtained at 40 degree , 50 degree , and 60 degree C for log K prime were minus 16. 3 plus or minus 0. 1, minus 16. 1 plus or minus 0. 6, and minus 15. 5 plus or minus 0. 2. The enthalpy change for the autosolvolysis reaction was found to be approximately 80 kJ multiplied by (times) mol** minus **1 over this temperature range. A curve fitting method for determining the initial composition of this ionic liquid during a titration is also described.
