摘要
在 2 98 15K和 30 8 15K下用振动管密度计在全浓度范围内测量了叔丁基甲醚 (TBME)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 4个二元混合物的VE 均为负值 ,顺序为 :间二甲苯 >对二甲苯 >乙苯 >邻二甲苯。
Excess molar volumes VE are reported for binary mixtures of tert-buthyl me thyl ether with o-xylene,m-xylene,p-xylene, and ethylbenzene at 29 8.15 K and 308.15 K. For each of these mixtures,VE is negative. The plot of VE vs x is nearly symmetric over the entire mole-fraction range.Th e excess molar volumes VE decrease in the order m-xylene>p-xylene> ethylbenzene>o-xylene.
