ABSTRACT
The excess molar enthalpies (HEm ) for the binary mixtures of trimethyl phosphate (TMP) with alkanols {CH3(CH2)nOH, n = 0 3} have been measured with an isothermal calorimeter at 298.15K and atmospheric pressure. The HEm values are positive for all the mixtures over the whole composition range. The values increase in the order methanol less than ethanol less than 1-propanol less than 1-butanol. The experimental results have been correlated with the Redlich Kister equation.
