Sažetak

The kinetics of the thermal degradation of n-propylbenzene
was studied by pyrolysis gas chromatography. The sample was
pyrolyzed in the gas phase, in a gold capillary tube inserted in
the micro flow reactor system that was directly connected to the
gas chromatograph. The degradation products were analyzed on a
glass capillary column with silicone rubber SE-30 as the liquid
phase. The kinetic data was obtained through qualitative and
quantitative analys1is of the degradation products. The results show
that the pyrolysis of n-propylbenzene is a first order reaction
with an activation energy of 44.0 kcal**/mol.
