间十五烷基酚的正丁醇溶液密度和粘度测定及关联
首发时间:2009-07-23
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粘度。结果表明,在测定范围内,密度与粘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。用VTF方程对数据关联,总的平均相对偏差为1.32%,标准偏差为1.67%。

Determination and Correlation of the Densities and Viscosities for 3-pentadecylphenol +n-butanol System
Abstract:In this paper, 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. The experimental data were regressed with VTF equation, the total average relative deviation is 1.32%, and the total standard deviation is 1.67%.
Keywords: 3-pentadecylphenol n-butanol density viscosity
