Gas chromatographic retention indices of trimethylsilyl derivatives of terpene alcohols

Abstract

This paper presents the experimentally determined retention indices (RI TMS) for a set of 75 silylated terpenols (33 monoterpenols and 42 sesquiterpenols). The attempt was made to assess the dependence of RI TMS on RI (for non-silylated terpenols) and on RI Ac (for acetylated terpenols). Satisfactory linear regression parameters (RI TMS = b 0 + b 1RI) were observed for tertiary substituted monoterpenols and primary or secondary substituted sesquiterpenols. The mass spectra of silylated terpenols that were not found in the available literature are in Supplementary information.
