Identification of isomeric alkylarenes with the use of additive relations for the evaluation of gas-chromatographic retention indices

Abstract

With the use of mono- and disubstituted C14-C16 alkylarenes as an example, it was found that, in many cases, the simplest additive relations for the estimation of gas-chromatographic retention indices make it possible to unambiguously identify the isomeric products of organic reactions even without the application of mass-spectrometric data. The simplest increments of different structural transformations of molecules, for example, CH3 → C6H5 and H → C6H5, remain of importance in algorithms of this type; however, the use of procedures with no increments for the assembly of target structures is more convenient.
