The enthalpies of solution of monoglyme, diglyme, triglyme, tetraglyme, pentaglyme and hexaglyme in N,N-dimethylforamide+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-dimethylforamide+propan-1-ol mixtures on the solution enthalpy of glymes in this mixtures has been analyzed.

的单甘醇二甲醚，二甘醇二甲醚，三甘醇二甲醚，四甘醇二甲醚，pentaglyme的溶液和hexaglyme在焓Ñ，Ñ -dimethylforamide +丙-1-醇的混合物已经在298.15 K.在的混合物甘醇二甲醚分子的优先溶剂化过程已经测量Ñ，Ñ已经讨论了将二甲基甲酰胺与甲醇或丙-1-醇一起使用。然后，计算了DMF，PrOH和MeOH对甘醇二甲酸酯类（–CH ₂ –和–O–）的溶剂化焓的贡献。基于所获得的数据，已经分析了N，N-二甲基甲酰胺+丙-1-醇混合物的结构和能量性质对该混合物中甘氨酸的溶液焓的影响。
