oa South African Journal of Chemistry - Excess molar enthalpies and excess molar volumes on mixing an aromatic compound with an alcohol at 298,15 K



Excess molar volumes for (toluene + methanol, + ethanol, + propan-1-ol, and + propan-2-ol) have been determined. These results together with the excess molar enthalpies and excess molar volumes for related binary systems of (benzene, toluene, o-, m-, p-xylene, and mesitylene + methanol, + ethanol, + propan-1- ol, and + propan-2-ol) are compared and discussed in terms of the influence of the methyl groups on the benzene ring. The excess molar volume results for mesitylene mixtures do not fit the patterns generated by the other aromatic systems.
