The measured enthalpy changes are close approximations of the partial molar enthalpies of solution of the alcohols in surfactant solution. Reported values of the partition coefficient K c derived from self-diffusion measurements using the Fourier transform NMR pulsed gradient spin-echo method were used ...
The determined enthalpy change. for 1-pentanol and 3-methyl-1-butanol systems were -80.4/120 kJ mol -1 and -203.0/254.7 kJ mol -1 respectively, indicating exothermic/endothermic extraction processes. The isomer 3- methyl -1-butanol gave a higher extraction efficiency after a three-stage ...
