✦ Synopsis

The Kovats retention indices of a large number of alkylbenzenes on different selective phases were determined. On the basis of incremental values, SI, on SE-30 as the liquid phase, the alkylbenzene degradation products were identified. The retention indices derived using homeomorphism factors for particular components were in very good agreement regardless of the parent compound and substituents used in deriving the retention data.

The incremental values for 38 alkyl and alkenyl substituents were determined, and the results obtained permitted the identification of more than 80 aromatic compounds evolved from alkylbenzene pyrolysis.
