Title: Excess Molar Enthalpy For Methanol, Ethanol, 1-propanol, 1-butanol + N-butylamine Mixtures At 288.15 And 308.15 K At Atmospheric Pressure : Measurements And Modeling Using Eras Model
Author: Checoni R.F.
Abstract: Experimental data of excess molar enthalpy (H mE ) of binary liquid mixtures containing (methanol or ethanol or 1-propanol, or 1-butanol) + n-butylamine mixtures have been determined as a function of composition at temperatures 288.15 and 308.15 K, at atmospheric pressure, using a modified 1455 PARR mixture calorimeter. The H mE values are negative for both systems over the whole composition range. The applicability of the ERAS Model to correlate H mE of mixtures studied is tested, and the agreement between experimental and theoretical results is satisfactory. The model results are discussed in terms of the cross-association interactions with temperature variation as well as in terms of the variation of the carbon chain in the alcohols presents in the mixtures. © 2009 Akadémiai Kiadó, Budapest, Hungary.
