Abstract
Studies are connected with the analysis and interpretation of the excess thermodynamic properties of aqueous and non- aqueous mixtures of alkyl poly (ethylene glycol) monoethers which have the generic formula CmH2m+1{o (CH2)2}nOH; which is conveniently abbreviated to CmEn. Excess thermodynamic properties, which depend on the composition temperature, and pressure, are of great importance in helping to understand the nature and extent of the pattern of molecular aggregation that exists in (water + an amphiphile) mixtures, resulting from molecular interactions between the components. Also, there have been some interesting recent investigation of (amphiphile + an organic solvent) systems designed to provide information about the nature of amphiphile aggregates. A comparative study of the excess thermodynamic properties provides evidence of the disruption of the amphiphile aggregates when the organic component is substituted for water.
