利用比重瓶和乌氏粘度计,测定了283.15K～313.15K条件下,间十五烷基酚的正丁醇溶液在不同组成下的密度与黏度.结果表明,在测定范围内,密度与黏度均随着温度的升高而降低,随着间十五烷基酚质量摩尔浓度的增大而增大,同时也计算了间十五烷基酚正丁醇溶液的表观摩尔体积.用VTF方程对数据关联,分别拟合得到两个关联方程,总的平均相对偏差为1.32%,标准偏差为1.67%.

Densities and viscosities of 3-pentadecylphenol + n-butanol system at 283.15K ～ 313. 15K were measured by calibrated pyenometer and Ubbelohde-type capillary viseometer. The results show that: both den-sities and viscosities decrease while the temperature increases, and increase with increasing molalities of 3-pentadeeylphenol. At the same time, the apparent molar volumes of 3-pentadeeylphenol in n-butanol is also calculated. The experimental data were regressed with VTF equation, the total average relative deviation is 1.32% , and the total standard deviation is 1.67%.
