项目摘要
The experimental data of the surface tension and saturated liquid density for alcohol and 1-butanol aqueous solution were obtained. The sample purity for ethanol and 1-propanol were 99.5 mass%. The sample purity for 1-butanol, 1-pentanol were 99.0 mass% and 98.5 mass%. The sample purity for 1-hexanol and 1-heptanol were 98.0 mass%.The surface tension was measured by the differential capillary rise method. In this study, five capillaries that inner radii are 0.2754±0.0003 mm, 0.3653±0.0003 mm, 0.6475±0.0002 mm, 0.7526±0.0009 mm and 0.8541 ± 0.0003 mm, were used. Experimental data of ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol and 1-heptanol were obtained in the temperature range between 273 K and 341 K. The uncertainty of temperatures and surface tension measurements are estimated to be within ±20 mK and ± 0.1 mN/in, respectively.In addition, on the basis of these data, the surface tensions as well as saturated liquid density correlations were made by least squares fitting. The surface tension correlation of ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol can reproduced with the average deviation of ± 0.05 mN/m, ± 0.06 mN/m, ± 0.07 mN/m, ± 0.10 mN/m, and ± 0.59 mN/m, respectively. The saturated liquid density correlation of both ethanol and 1-butanol can reproduced with the average deviation within ± 0.01 kg/m^3.Sixteen surface tension data of 1.0 %1-butanol aqueous solution were obtained in the temperature range between 283 K and 348 K. Fifteen surface tension data of 1.5 %1-butanol aqueous solution were obtained in the temperature range between 289 K and 355 K. In addition, saturated liquid densities data of 0.5 %, 1.0 %, 1.5 % and 2.0 % 1-butanol aqueous solution were obtained in the temperature range between 275 K and 353 K. On the basis of the present data, the correlations of the density correlations were made by least squares fitting.
得到了乙醇和正丁醇水溶液的表面张力和饱和液体密度的实验数据。乙醇和正丙醇的样品纯度分别为99.5%和99.5%。正丁醇、正戊醇的样品纯度分别为99.0%和98.5%。样品中正己醇和正庚醇的纯度分别为98.0%和98.0%,采用差示毛细管上升法测定表面张力。内径分别为0.2754±0.0003 mm、0.3653±0.0003 mm、0.6475±0.0002 mm、0.7526±0.0009 mm和0.8541±0.0003 mm。在273~341K温度范围内获得了乙醇、正丙醇、正丁醇、正戊醇、正己醇和正庚醇的实验数据,温度和表面张力的测量不确定度分别在±20mK和±0.1mN/in以内,并在此基础上进行了表面张力和饱和液体密度的最小二乘拟合。乙醇、正丙醇、正丁醇、正戊醇、正己醇、正庚醇的表面张力关联式的平均偏差分别为±0.05mN/m、±0.06mN/m、±0.07mN/m、±0.10mN/m和±0.59mN/m。乙醇和正丁醇的饱和液体密度关联式可重现,平均偏差在±0.01 kg/m~3以内。在283~348 K温度范围内,获得了1.0%正丁醇水溶液的16个表面张力数据。在275K~353K温度范围内,得到了1.5%和2.0%正丁醇水溶液。在此基础上,用最小二乘法拟合出了密度关联式。
