The excess molar enthalpies of some alkan-1-ol (methanol to hexanol)/iso-propanol binary systems have been measured at 298.15K under ordinary pressure using LKB2277 Bioactivity Monitor. The excess enthalpies of propanol, butanol and pentanol/iso-propanol have been measured at 308.1K and 313.15K. The parameters of polynomial equation for fitting the experimental results are also reported.

Key words: ETHANOL, METHANOL, BUTANOL, ENTHALPY, ISOPROPANOL, PROPANOL, PENTANOL, HEXANOL
