【摘要】 建立了色谱法扩散系数测定装置。在常压下，２９８．２Ｋ～３３３．２Ｋ的范围内测定了苯、甲苯、对二甲苯、邻二甲苯、乙基苯、均三甲苯、萘、菲、蒽和联苯等十种芳烃在无水乙醇中的无限稀释扩散系数，共４０点，用Ｗｉｌｋｅ－Ｃｈａｎｇ方程进行了关联更多还原

【Abstract】 An apparatus for measuring the liquid diffusion coefficient by chromatographic broadening technique was established. Diffusion coefficients were measured for benzene, toluene, p-xylene, oxylene, ethylbenzene, 1, 3, 5-trimethylbenzene. naphthalene,phenanthrene, anthracene , biphenyl in ethanol from 298. 2K～333.2K. The data were correlated with Wilke-Chang equation ,and the average deviation of correlation is 3. 80%。更多还原
