|Title:||Thermodynamic Parameters For Transfer Of Resorcinol Monoethers From Water To Heptane And To Propylene Carbonate. Derivation And Analysis Of Group Transfer Thermodynamic Parameters|
|Abstract:||Partition coefficients have been measured over a range of temperature for transfer of a series of resorcinol monoethers from water to heptane and to propylene carbonate (all solvents mutually saturated). These data have been used to evaluate ΔGtrs, ΔHtrs and ΔStrs. Further analysis allows assignment of ΔGtrs, ΔHtrs and ΔStrs values for transfer of a lipophilic group (CH2) and the 'parent' structure between the selected solvents. Transfer of a CH2 group is shown to be accompanied by a zero enthalpy change, whereas transfer of the parent structure results in ΔHtrs values dependent upon the non-aqueous solvent involved. These data are discussed in terms of partitioning and the use of a suitable bulk solvent to represent a biological lipid phase.|
