(60 m ꢄ 0.32 mm, film thickness 25
lm, oven temperature 60 °C,
N2 carrier flow 114 l/min) and a flame ionization detector (FID,
250 °C detector temperature). After the thermostatization time a
sample was automatically drawn from the gas phase in the vial.
The product was analyzed by the GC retention time versus authen-
tic samples of cyclohexene and cyclohexane. Hydrogenation con-
version (%) was calculated from the obtained cyclohexane-to-
cyclohexene peak area and compared to a calibration curve from
different ratios of given cyclohexene/cyclohexane mixtures which
had been measured under identical headspace conditions.
