苯多酚衍生物的气相标准生成焓与其共振能和取代基数目的线性关系

RELATIONSHIP BETWEEN THE RESONANCE ENERGIES AND THE NUMBER OF SUBSTITUENT AND THE GAS PHASE STANDARD ENTHALPIES OF FORMATION THE HYDROXY-SUBSTITUTED PHENL HYDROXIDE DERIVATIVES

本文根据生成焓的加和性规则得出了苯多酚衍生物的气相标准生成焓分别与其共振能（RE）和取代基数目（n）之间的线性关系：3≥n≥0，β’为衍生物中取代基的次级效应与其间应的苯多酚行生物中取代基的次级效应之差，（1）、（2）式的计算值与实验值都没吻合，相关系数分别为0．9994和1．0000。

In this paper, A relationship between the resonace energies and the number of substituent and the gas phase standard enthalpies of formation of hydroxy-substituted phenyl hydroxide derivaivaives was obtained according to the additivity rule of the enthalpies of formation: There, 3≥n≥o, β’ is differ value of second effect of substituent in derivatives from which of meta-hydroxy substituted phenyl hydroxide derivatives. the calculated values are good agree with experiment. Relalive coefficient are respectively 0. 9994 and 1.0000.
