| Abstract: | Branched-chain alcohols with from one to eight carbon atoms have been analysed by gas chromatography using thermal conductivity and flame-ionization detectors. The specific retention volumes, Vg, and the retention indices relative to normal alcohols were determined for all the compounds, and the effects of the branching and of the position of the hydroxyl groups have been investigated. Boiling points, vapour pressures, molecular volumes were correlated with the measured retention values. The activity coefficients at infinite dilution and the normalized activity coefficients were calculated, and their influence on the separation is discussed. The results are compared with the behaviour of branched-chain halogenoalkanes on polar and non-polar stationary phases. |
