摘要
The enthalpies of solution of monoglyme, diglyme, triglyme, tetraglyme, pentaglyme and hexaglyme in PI,Ndimethylforamide+propan-1-ol mixtures have been measured at 298.15 K. The preferential solvation process of glymes molecules in the mixtures of N,N-dimethylformamide with methanol or propan-1-ol has been discussed. Then the contribution of DMF, PrOH, and MeOH to the solvation enthalpy of group (-CH2- and O-) of glymes has been calculated. On the basis of the obtained data, the effect of the structural and energetic properties of the N,N-climethylforamide+propan-1-ol mixtures on the solution enthalpy of glymes in this mixtures has been analyzed.
