Tetramethylammonium hydroxide (TMAH) thermochemolysis of softwood lignin provides Z/E-1-(3,4-dimethoxyphenyl)-2-methoxyethene (5) and erythro/threo-1-(3,4-dimethoxyphenyl)-1,2,3-trimethoxypropane (9), as products derived from b-aryl ether subunits. To increase the contribution of 9, Japanese cedar (
Thermally assisted hydrolysis and methylation (THM) with tetramethylammonium hydroxide (TMAH) was performed on spruce milled wood lignin (MWL) in order to investigate THM parameters. The objective was the maximization of information on lignin structure. The main emphasis was laid on the formation of
