【摘要】 本文用气相色谱法测定了43种体系在癸烷基磷酸铈色谱柱中的保留值,吸附焓变、吸附熵变.证明:(?)保留值、吸附焓变仅取决于吸附质与吸附剂之间的色散力作用大小.并且与同系物的碳原子数之(?)存在着好的线性关系.在色谱柱上存在“热力学补偿效应”,解释为吸附质分子在吸附剂上呈现出(?)分子层吸附排列,而且随吸附量的增加吸附中心数成比例减少的缘故.更多还原

【Abstract】 The thermodynamic functions for the adsorption of several dozen compounds have been dertermined by gas chromatographic method. It is found that InVR、△H only depend on the disperson force between the adsorbete and the adsorbent. Good linear relation between △H or InV’ R and the carbon number of compound in a homologue have been found. We also found the"thermodynamic compensation effect"on this new stationary. and thougat that it is be-cause of monomolecular distribution and decrease of adsorbent "central point" on the surface of adsorbent along with the increasing of adsorbent volume.更多还原
