摘要

Excess enthalpies of binary mixtures between each of alkane-1-amines {CnH2n+1NH2, n = 3-8} and methyl methylthiomethyl sulfoxide (MMTSO) or dimethyl sulfoxide (DMSO) have been determined at 298.15 K. All mixtures showed positive enthalpy chances over the whole range of mole fractions. The limiting excess partial molar enthalpies of the aliphatic amines, H-1(E,infinity) of all the mixtures with MMTSO or DMSO studied were smaller than those of MMTSO or DMSO, H-2(E,infinity), respectively. Linear relations are obtained between limiting excess partial molar enthalpies and number of methylene groups. (C) 2003 Elsevier Science B.V. All rights reserved. [References: 18]
