摘要 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 pycnometer and Ubbelohde-type capillary viscometer.The results show that： both densities and viscosities decrease while the temperature increases,and increase with increasing molalities of 3-pentadecylphenol.At the same time,the apparent molar volumes of 3-pentadecylphenol 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%.
