Abstract:Enthalpy of solution at 25°C of squalane in butyl alcohols and 1-octanol is determined calorimetrically. The endothermic effect of dissolution increases in the order 1-OctOH < BuOH < i-BuOH < t-BuOH. A linear correlation is found between the enthalpies of solution of squalane and hexadecane, from which the enthalpy of solution of squalane in methanol is determined. The contributions of the cavity formation and solute-solvent interaction to the enthalpy of solution are estimated by multiple regression analysis. The enthalpy of cavity formation is only slightly dependent on the length of the main chain of an alcohol and also on the branching type, varying in the order 1-OctOH ∼ BuOH ∼ i-BuOH < MeOH ∼ s-BuOH < t-BuOH. Interaction of squalane with alcocols increases in the order MeOH < t-BuOH < BuOH < ∼ i-BuOH ∼ s-BuOH < 1-OctOH.
