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(qx)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。

关键词: 气相碱性, 质子, 醚, 亲和能, 极化效应指数, 醇, 脂肪族胺

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.

Key words: PROTONS, ETHER, ALCOHOL, ALIPHATIC AMINES
