摘　　要：测制了二氯甲烷环已酮， 二氯甲烷 Ｎ， Ｎ二甲基甲酰胺的固液平衡相图． 相图表明形成了１∶１ 的稳定化合物 Ｃ６ Ｈ１０ Ｏ· Ｃ Ｈ２ Ｃｌ２ 和 Ｈ Ｃ Ｏ Ｎ （ Ｃ Ｈ３）２· Ｃ Ｈ２ Ｃｌ２ ． 计算出由固体组分生成这些固体分子间化合物的摩尔焓变， 对计算结果进行了讨论．Melting temperatures were measured and the solid liquid phase diagrams were constructed for dichloromethane +cyclohexanone, or N,N dimethylformamide.Solid addition compounds form with the empirical formulae: C 6H 10 O·CH 2Cl 2 and HCON(CH 3) 2·CH 2Cl 2 The changes of molar enthalpy of formation of intermolecular compounds from solid components were calculated The calculations show that the formation of solid intermolecular compounds is attributed to a charge transfer interaction

关 键 词：相图 固液平衡 固体分子间化合物 摩尔焓变
