Relation de topologie-information entre la structure de cétones et d'esters aliphatiques saturés et leur temps de rétention en chromatographie gaz-liquide

Abstract A topology-information relationship between the structures of ketones and saturated aliphatic esters and their retention times in gas chromatography The retention times of forty-five saturated aliphatic esters and forty saturated aliphatic ketones measured by gas-liquid chromatography on an SE-30 column at five temperatures between 120 and 210° have been correlated with their structures using the DARC topological system. Previously calculated parameters for the two groups of compounds have been compared. It has been shown that the logarithms of the relative retention times of eighty-two compounds can be accurately correlated with their structure by means of a sixteen-parameter equation.
