Excess molar enthalpies for binary mixtures of trimethyl phosphate with alkanols {CH3(CH2)nOH, n = 0–3} at 298.15 K

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