汽油与醇混合物作为动力燃料已日益广泛。为了研究醇中杂质水对这种新型动力燃料有关热力学性质的影响,Letcher等测定了正庚烷-水-醇类三元体系的液-液平衡状态。本文报道C_6H_(14)-C_2H_5OH和C_6H_(14)-C_2H_5OH-H_2O混合物在303.15K的密度,并由此算得正已烷的表观摩尔体积和偏摩尔体积。
Gasoline and alcohol blends have become increasingly popular as fuel. In order to study the effect of impurity water in alcohols on the thermodynamic properties of this new fuel, letcher et al. Determined the liquid-liquid equilibrium of n-heptane-water-alcohol ternary systems. In this paper, the density of C_6H_ (14) -C_2H_5OH and C_6H_ (14) -C_2H_5OH-H_2O mixture at 303.15K is reported, and the apparent molar volume and partial molar volume of n-hexane are calculated.
