Excess Molar Enthalpy of Mixing of Binary Mixtures of 2-butanone with Aromatic Hydrocarbons and Cyclohexane at T = 298.15 K.

Excess enthalpy of mixing for 2-butanone with benzene, toluene, o-, m-, p-xylene and or cyclohexane binary mixtures have been determined with 2-drop calorimeter and data is applied to Redlick-kister equation at temperature 298.15 K. A number of experimental as well as theoretical studies on thermodynamic properties for ketones with alkanes1-5, alkenes 6, aromatic hydrocarbons7-10, alcohols11-15, ethers16-17, esters18, amides19-20 and amines21 have been reported in literature. Among them, systemic data for ketones + aromatic polar solvent are relatively rare7-10. Ketones are characterized by dipoledipole interactions in the pure state22-23.
