Homologous Increments of Gas Chromatography Retention Indices As A Characteristic of Organic Compounds Polarity
The properties of homologous increments of gas chromatography retention indices were considered, iRI = RI - 100int (M/14), where M is the molecular mass of the compound, and RI is its retention index. As a result of their correlation with other characteristics of organic compounds (normal boiling points, dielectric constants, dipole moments, retention indices and their differences for standard polar and non-polar phases, boiling point indices, molecular weights and molar refractions and their differences) it was shown that iRI values can be used as additional characteristics of polarity.
