摘要:

疏水常数是有机污染物的亲脂性参数,是决定有机物分子在环境中转移、分配以及通过生物膜吸收,在组织内渗透、消除的重要性质,是环境科学研究和环境保护评价的一个重要参数.采用摇瓶法,用高效液相色谱仪测定了典型芳香化合物中的6种烷基苯和7种芳胺类化合物在温度为25～60℃下的疏水常数;根据化工热力学的相平衡理论,提出了疏水常数随温度变化的热力学关系,由实验数据计算确定了相际传递焓△H和相际传递熵△S;并讨论了疏水常数的温度效应系数,与文献值有相同的数量级.

Abstract:

The hydrophobic constant is a lipophilic parameter of organic pollutants, which is an important quality that determines the transfer, distribution, absorption and infiltration and elimination of organic molecules in the environment, and is an important parameter for environmental science research and environmental protection evaluation. The hydrophobic constants of 6 alkylbenzenes and 7 aromatic amines in typical aromatic compounds at a temperature of 25~60 °C were determined by high performance liquid chromatography. According to the phase equilibrium theory of chemical thermodynamics, the thermodynamic relationship of hydrophobic constant with temperature was proposed, and the interphase transfer enthalpy△H and interphase transfer entropy △S were determined by experimental data. The temperature effect coefficient of the hydrophobic constant is discussed, which has the same order of magnitude as the literature value.
