Characterization of peatified and coalified wood by tetramethylammonium hydroxide (TMAH) thermochemolysis

International Journal of Coal Geology, 1996
Abstract Seven samples of peatified and coalified wood, varying in rank from peat to subbituminous coal, have been analyzed using a new technique: thermochemolysis with tetramethylammonium hydroxide (TMAH). The preserved lignin in the coal undergoes thermochemolysis reactions when subjected to treatment with TMAH at 300°C for 10 min, yielding a ...

Characterization of dissolved organic matter by thermochemolysis with tetramethylammonium hydroxide

2019
Most of the dissolved organic matter (DOM) in the oceans is of a refractory nature and represents that faction of marine biological productivity that has survived microbial mineralization. Williams and Druffel (1987) deduced that only a small fraction of DOM originates form exchange with the terrestrial carbon pool.
