Excess molar enthalpies of dichloromethane +acetone or + dimethyl sulfoxide or + tetrahydrofuran or + 1, 4-dioxane at the temperature 313.15 K

Excess molar enthalpies H^E at T= 313.15 K have been determined for dichloromethane (CH₂Cl₂) + acetone (CH₃)₂CO or + dimethyl sulfoxide (CH₃)₂SO) (DMSO) or + tetrahydrofuran (C₄H₈O) or + 1, 4-dioxane (C₄H₈O₂). The excess molar enthalpies for all systems are exothermic in nature. The excess partial molar enthalpies of the components H^E_{m, 1}, and H^E_{m, 2} were calculated from HE data. These results indicate the existence of specific interactions between all these components.
