Structural differences in lignin between Eucalyptus clones determined by analytical pyrolysis-gas chromatography/mass spectrometry
In this study, a large number of wood samples from several species of Eucalyptus, including E. grandis, E. urophylla, E. globulus, E. dunnii, E. camaldulensis and their crossing were characterized by pyrolysis-GC/MS method. All the measurements were done directly from the Eucalypus wood samples. S/G ratios were calculated for all guaiacyl and syringyl lignin pyrolysis derivatives. The results w...
متن کاملMulti-Residue Analysis of Pesticides in Pistachio Using Gas Chromatography-Mass Spectrometry (GC/MS)
Background: Analysis of pesticide residues in food and other environmental commodities have become an essential requirement for consumers, producers, food inspectors and authorities. This study is focused on validation of an accurate, rapid and reliable method for multi-residual analysis of pesticides in pistachio as a strategic crop for export and one of the main nuts in Iranian food basket.Me...
متن کاملDegradation of Lignin by Pyrolysis
Fast pyrolysis is an efficient technique for thermal degradation of lignin to bio-oils containing bio-phenols for the synthesis of adhesives, resins, and polymers. Lignin has a complex structure, and hence a large number of pyrolytic components are generated during the pyrolysis process. The composition of the pyrolytic products depends on the type of lignin, temperature, types of catalyst, and...

متن کاملIdentifying acetylated lignin units in non-wood fibers using pyrolysis-gas chromatography/mass spectrometry.
A series of non-wood plant fibers, namely kenaf, jute, sisal and abaca, have been analyzed upon pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of the whole material. The pyrolysis products mainly arise from the carbohydrate and lignin moieties of the fibers. The lignin-derived phenols belonged to the p-hydroxyphenylpropanoid (H), guaiacylpropanoid (G) and syringylpropanoid (S) struct...
