Gas Chromatographic Identification of 2, 6-Disubstituted-trans-decalins using Retention Indices

Abstract

Thirty one 2, 6-disubstituted-trans-decalins were chromatographed on carbowax 20M and OV-1 columns, and the retention volumes were converted into the Kovats' retention indices. The increments of some substituents (OH, OCH₃, Cl, OAc, CN, COOCH₃, C₆H₅) were determined on the basis of the additivity rule. Elution characteristics of the investigated stereoisomers were reported and discussed.
