Abstract

The effects of temperature, atmosphere, sample and particle size were examined on the formation of selected smoke compounds from tobacco. The study used on-line pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and off-line pyrolysis experiments in a pyrolyzer with subsequent GC/MS measurements. The Py-GC/MS experiments were carried out in helium, while the experiments with off-line analysis were made in nitrogen as well as in a mixture of 2% (v/v) O2 and 98% (v/v) N2. Two different blends of tobacco (Virginia and Burley) and some precursor compounds (cellulose, quercetin dihydrate, chlorogenic acid hemihydrate) were examined. The formation of 1,3-butadiene, benzene, naphthalene, phenol, hydroquinone and catechol were studied at 450, 600 and 900 °C. It was found that the formation of butadiene, benzene and naphthalene was promoted, while phenol formation was hindered by the introduction of 2% oxygen. The results verified that cellulose and polyphenols are source compounds of butadiene, benzene and naphthalene at 900 °C. The polyphenols may be considered as precursors of catechol, and chlorogenic acid as a precursor of hydroquinone at lower temperatures (
