摘要
利用比重瓶和乌氏粘度计,分别测定了萘-甲苯体系和萘-二甲苯体系(293.15~318.15)K在不同组成下的密度与黏度.从测量的数据中计算得到了表观摩尔体积.通过对实验结果进行拟合,得到了适宜的拟合参数和实验值与计算值的标准偏差.
The densities and viscosities of naphthalene + toluene and naphthalene + xylene mixtures have been determined experimentally under normal atmospheric pressure over the entire molality range from(293.15 to 318.15) K.The apparent molar volumes of naphthalene were calculated from experimental measurements.Results were fit to obtain the appropriate parameters and standard deviations between the measured and fitted values.
