The Study of Pyrolytic Products of Polymer Materials by Mass-Spectroscopy The Mass-Spectroscopy of Pyrolytic Products of Wood Components

Abstract

Mass spectrometric study was carried out in the analysis of gaseous mixtures produced by the pyrolysis of wood components under various conditions. Following compounds were detected as pyrolytic products: hydrogen, carbon monoxide, carbon dioxide, methanol, ethanol, acetone, methyl ethyl ketone, dimethyl furan, methyl furan, acetic acid, acetaldehyde, methane, acetylene, ethylene, ethane, propane, propylene, butene, butane, water, benzene and toluene. As a result of the pyrolytic studies under varying conditions, it was found that the composition the pyrolytic product mixture was greatly influenced by the pyrolysis temperature and duration. The results of the present work suggest that most of the aromatic compounds are produced by the pyrolysis of lignins. From the result of this work, mass spectrometry seems to be an effective method for the analysis of the pyrolysis product of wood components.
