Characterization of bio- and geopolymers by thermochemolysis with tetramethylammonium hydroxide (TMAH)
- Pennsylvania State Univ., University Park, PA (United States); and others
A new analytical procedure, tetramethylammonium hydroxide (TMAH) thermochemolysis, was used to assess the structural characterization of a variety of bio- and geopolymers. The technique yields the methyl esters of carboxylic acids and the methyl ethers of hydroxyl groups, rendering them volatile for gas chromatographic analysis. Use of this technique for the analysis of polar macromolecules has greatly enhanced product yields and produces some products not observed by conventional pyrolysis. This procedure can be conducted at subpyrolysis temperatures in sealed glass tubes, which means that it can be easily implemented in any laboratory having gas chromatographic capabilities, in contrast to other chemolytic or pyrolytic procedures. In general, the data demonstrate that this technique provides good preservation of the original carboxyl and hydroxyl groups present in the macromolecular structure of bio- and geopolymers owing to protection of the functional groups from thermal decomposition reactions.
