Pyrolysis of lignin in the presence of tetramethylammonium hydroxide (TMAH): products stemming from beta-5 substructures.
Lignin model compounds, synthetic lignins, and cedar wood have been analyzed by pyrolysis-gas chromatography(-mass spectrometry) in the presence of tetramethylammonium hydroxide (TMAH) to examine the behavior of beta-5 substructures specifically under these conditions. Two model compounds contained a beta-5 linkage and a gamma-CH2OH group. The phenolic model compound produced stilbene products ...
متن کاملTetramethylammonium hydroxide (TMAH) thermochemolysis of lignin: behavior of 4-O-etherified cinnamyl alcohols and aldehydes.
The thermochemolytic behavior of 4-O-etherified cinnamyl alcohols and aldehydes in lignin was investigated in the presence of tetramethylammonium hydroxide (TMAH) (315 degrees C/4 s), using veratrylglycol-beta-(coniferyl alcohol) ether (1a), veratrylglycol-beta-(sinapyl alcohol) ether (1b), and veratrylglycol-beta-(coniferyl aldehyde) ether (2). The methylated products were monitored with gas c...
متن کاملThe application of C-labeled tetramethylammonium hydroxide (C-TMAH) thermochemolysis to the study of fungal degradation of wood
This paper presents the results from an assessment of the application of a new molecular analytical procedure, CTMAH thermochemolysis, to study the chemical modi®cation of lignin by white-rot and brown-rot fungi. This technique diers from other molecular chemolysis procedures (e.g. TMAH thermochemolysis and CuO alkaline oxidation) as it enables one to determine the amount of hydroxylated aroma...
