Application of the principle of structural analogy to the calculation of gas-chromatographic retention indexes from physicochemical properties of organic compounds

摘要

The possibility for calculating gas-chromatographic retention indexes of organic compounds on nonpolar polydimethylsiloxane stationary phases from the boiling temperatures of their structural analogs from other series was demonstrated. This technique can be used for calculating retention indexes of complex-structure compounds from the data on simpler compounds that are characterized more comprehensively by physicochemical constants. Errors in the technique suggested are no higher than the average standard deviations of randomized experimental indexes.
