摘　　要：在298.15K和308.15K下用振动管密度计在全浓度范围内测量了二(口恶)烷分别与邻二甲苯、间二甲苯、对二甲苯和乙苯构成二元混合物的过量摩尔体积VE。这四个二元混合物的过量摩尔体积VE均为正值。Excess molar volumes VE are reported for binary mixtures of,4-dioxane with o- xylene, m-xylene,p -xylene, and ethylbenzene at 298.15 K and 308.15 K. For each of these mixtures, VE is positive. The plot of VE vs x is an nearly symmetric over the entire mole- fraction range.
