Golovnya, T. Kuz'menko, N. Krikunova] The chromatographic indicator of the ability of substances to form associates in a pure liquid δT b.p. proposed in our previous study was used to estimate the capacity for self-association of alkyl-substituted imidazoles, pyrazoles, pyrroles, oxazoles, isoxazoles, pyridazines, pyrimidines, pyrazines, and pyridines. Alkyl substituents introduced in heterocyclic compounds decrease the δT b.p. values, which is consistent with the data on the heats of self-association of heterocyclic compounds in pure liquids. The reasons for the difference between the boiling point of a compound at standard pressure and its "gas-chromatographic boiling point” are discussed.
