极化效应指数与脂肪族胺、醇和醚气相碱性的关系

Relation Between the Polarizability Effect Index and the Gas Phase Basicity of Fatty Amine, Alcohol and Ether

脂肪族胺、醇和醚的气相质子亲合能(PA)与N.O原子所带电荷(q_x)以及烷基的极化效应指数(PEI)的关系可表示为 其中a、b、c为系数。回归分析结果表明,上式较好地表达了脂肪族胺、醇和醚的气相碱性变化规律。

It can be expressed as the function of the atomic charge qx (X - N or O atom) and the Polarizability Effect Index (PEI) of alkyl group for the gas phase Proton Affinity (PA) of fatty amine, alcohol and ether Here, the a, b and c are empirical constants, The results of regression analysis showed that above equation is a good expression for the gas basicity change rule of amine, alcohol and ether.
