摘要

研究了互变异构对RM的影响。讨论了对色谱效应的一般性质，并得到了用色谱法验证互变异构存在的方程。如果从原型化合物的研究中获得足够的数据，其中每一种形式的互变异构基团不受其他本构效应的影响，则有可能通过这些方程来计算给定化合物中互变异构平衡的位置。以噻吩(2-羟基噻吩)、对亚硝基苯酚和4-亚硝基- 1 -萘酚的互变异构体为例说明了这一过程。接下来的程序取决于许多群和结构ΔRM参数对马丁方程的可加性原理的依从性。

Paper chromatography and chemical structure

The effect of tautomerism on R_M has been studied. The general nature of the effect on chromatography is discussed and equations obtained by means of which the existence of tautomerism can be verified chromatographically. If sufficient data are available from the study of archetypal compounds in which each form of the tautomeric group occurs free from other constitutive effects, it is possible, by these equations, to calculate the position of tautomeric equilibrium in a given compound. The procedure is illustrated with reference to the tautomerism of thienol (2-hydroxythiophen), p-nitrosophenol and 4-nitroso-I-naphthol. The procedure followed rests on the adherence of many group and structural ΔR_M parameters to the additivity principle of $Martin$ 's equation.
