O.  aSimultaneous pyrolysis and trimethylsilylation with N-methyl - (trimethylsilyl) trifluoroacetamide for the characterisation of lignocellulosic materials from kraft pulping.h[electronic resource]  c2018  aSimultaneous pyrolysis and trimethylsilylation (SPyT) with N-methyl-(trimethylsilyl)trifluoroacetamide (MSTFA) was used to characterise lignocellulosic materials from pine and eucalyptus obtained by kraft pulping. This approach protects the carboxyl groups and helps preserve the original structure of phenolic products during analytical pyrolysis, and so that pyrolysis and derivatisation occur simultaneously and the fragments of underivatised compounds are also silylatated. The SPyT products are representative for the structures present in carbohydrates and lignin of the investigated materials. The method is also suited to semi-quantitative evaluation also in terms of detection of condensed lignin structures in pulps and kraft lignins.  aBiomass  aGas chromatography  aMass spectrometry  aBiomassa  aCromatografia Gasosa  aAMDIS  aAutomated mass spectral deconvolution and identification system  aDerivatisation  aEspectometria  aKováts retention index  aMonomers  aSilylation1 aTOMASI, J.
