摘要
本文用改进的Dvo(?)k-Boubl(?)k平衡釜,采用微型蒸馏和气相色谱模拟实沸点蒸馏技术相结合的方法,测定了丙酮-油、甲苯-蜡两个系统在101.33kPa下的汽液平衡数据。用一种新的连续热力学方法——导数法进行关联,连续组分间的交互作用参数假设为常数,而将溶剂与连续组分间的交互作用参数表达为连续组分摩尔质量的函数,取得了满意的结果.
By adopting the modified Dvorak-Boublik equilibrium still and using the method of micro-distillation combined with the technique of simulated true boiling point distillation and gas chromatography for sample analysing, the VLE data have been determined at normal pressure for lube Oil fractionacetone system and wax (containing Oil)-toluene system.The data are correlated by a new continuous thermodynamics method-derivative method, where interaction parameters between continuous fractions are assumed to be constants and interaction parameters between solvents and continuous fractions are expressed as a function of molecular weight of continuous components. The results are satisfactory, indicating that this method is efficient and reliable.
