本文从理论上研究了分子结构参数对保留值变化规律式中参数a,b和c的影响,并用实验结果初步验证了理论推测.提出了参数a,b和c与分子结构参数van derWaals体积V_w、偶极矩μ_A和氢键作用能X_(AH)的定量关系;指出只有结构相关的化合物才有严格的参数a和c间的线性关系.在此基础上研究了非极性化合物、同系物和极性混合物在冲洗剂宽浓度范围内预测保留值的可行性. In this paper, the influence of molecular structure parameters on the parameters a, b and c in the variation of retention values ​​is theoretically studied, and the theoretical predictions are preliminarily verified with the experimental results. The relationship between the parameters a, b and c and the van der Waals volume V_w , The dipole moment μ_A and the hydrogen bond energy X_ (AH). It is pointed out that only structurally related compounds have a strict linear relationship between parameters a and c. On the basis of this, we have studied nonpolar compounds, homologues And polar mixtures predict the retention of values ​​over a wide range of concentrations of the rinse.
