Analysis of aliphatic biopolymers using thermochemolysis with tetramethylammonium hydroxide (TMAH) and gas chromatography–mass spectrometry [PDF]
Organic Geochemistry, 1998 Selected aliphatic biopolyesters (cutins, cuticles and a suberin) isolated from di erent plants have been analyzed using thermochemolysis with tetramethylammonium hydroxide (TMAH). This method consists of a high-temperature saponification/transesterification, and yields methyl esters of fatty acids and the methyl ethers of alcohols, which are ...
