An equation is proposed to determine the value of the partial molar enthalpy of solution of the substance under investigation from its retention indices. The values of the enthalpy of solution obtained for benzene, cyclohexane, diethylsulfide, di-n-propylsulfide, dimethyldisulfide, diethyldisulfide, n-propylmercaptan, n-butylmercaptan in apiezon-M and polyethyleneglycol-1000 have been for the first time determined by two methods: through the specific retention volumes and by means of our equation. The dependence of the partial molar ethalpy of solution and evaporation of n-hydrocarbons on the number of carbon atoms has been investigated. It has been experimentally shown that the homological difference between the enthalpy of evaporation and that of solution is practically equal in absolute value, amounting to {equal to or succeeds} 1 kcal/mole. 1970 Friedr.
