Resumen
CORNWELL, Edward y CORDANO, Gianni. Nueva proposición para predecir datos de retención obtenidos mediante cromatografía de gases de hidrocarburos derivados de las naftas. Rev. Soc. Quím. Méx [online]. 2003, vol.47, n.1, pp.38-43. ISSN 0583-7693.
regression equation for 64 naphta hydrocarbons is proposed to relate a new index (Cg), the Kovats index obtained in apolar chromatographic columns (Iapolar) and the chemical connectivity index order 1 valence type (χv1). The statistical profile of the proposed regression is similar to the reference model but with two easy-to-obtain, independent variables and a higher Fisher index. This permits a good approach to identify the hydrocarbons under study by means of the suggested equation with a maximum error of 4,1 % between the experimental and calculated Kovats indices.
