摘要: Although the effect of solvent on rate and position equilibrium chemical reactions has been known since last century, there are still no reliable exact methods for a quantitative description prediction such effects. Empirical parameters polarity great value in this respect can be derived with aid principle “linear relationships between free energies” (LFE relationships). The present article deals possibilities establishing reaction absorption series using solvent-dependent standard or absorptions organic compounds. Particular attention is merited by summary 24 most important empirical table ET(30) values 151 solvents. In addition to examples application these values, attempts improve LFE correlations singular multiparametric equations described.
