Abstract: | Summary The retention of hydrocarbons present in the C5 pyrolysis fraction of gasolines on the stationary phases squalane and methylsilicone oil JXR at 30, 40 and 50°C was investigated
by capillary gas chromatography. The unified retention indices of the hydrocarbons were also calculated on squalane. The retention
indices obtained on these two phases were interrelated and the quantitative relationship with the structure of the solutes
was studied.
Equations based on the unified retention indices calculated on squalane and some selected structural elements of the solutes
permit the calculation of their retention on methylsilicone with sufficient accuracy. |
