| Abstract: | By means of g. i. c., the activity coefficients at infinite dilution in the solvent bexatriacontane and squalane have been obtained for 11 solutes.The 11 solutes are heptane, hexane, pentane, carbon tetrachloride, diethyl ether, 2-propanol,1-propanol, ethanol, methanoe, acetone, 2-butanone. The infinite dilution partial molar excess enthalpies and entropies of the solute have been calculated from the temperature dependence of the activity coefficients. |
