Tetramethylammonium hydroxide (TMAH) is one of the most popular methylation reagents that have been increasingly used for the detection of organic compounds within a wide range of samples, such as soil, coal, lacquer, lignin, polymers and for in situ analysis of solid samples by space experiments. The analytical methods and instruments, experimental conditions, and the qualitative and quantitative analysis of organic compounds using TMAH thermochemolysis for the last 10 years were reviewed; additionally, the mechanism of TMAH thermochemolysis and TMAH degradation are overviewed herein. The objective of this paper is to give a broad view of the TMAH thermochemolysis analysis, to demonstrate how the technique can be used for the detection of organics on Mars and other planets, and to promote cooperation between different disciplines which may use thermochemolysis.

Pyrolysis is considered a promising method for polymer characterization (in the field of analytical pyrolysis) and for chemical feedstock recovery from plastic wastes (in the field of applied pyrolysis) because it can decompose any polymeric material into smaller molecules by applying heat alone in an inert atmosphere. Pyrolysis-gas chromatography (Py-GC) involves pyrolyzing polymeric materials in a micropyrolyzer and the subsequent direct GC analysis of pyrolyzates. Py-GC has immense potential for application in the fields of both analytical and applied pyrolysis, allowing rapid and accurate analysis of pyrolyzates. This is beneficial for elucidating microstructure and composition of polymers and for rapid screening of pyrolysis conditions for designing feedstock recycling processes. In this review, we examined latest research trends in Py-GC for application in polymer characterization, analysis of plastics in environment, and chemical feedstock recovery from plastics.

“…Similar water sensitivity is observed when using dimethylformamide dipropyl acetal as a propylation agent [20] and extensive drying of the sample is required prior to analysis. Flash pyrolyzation using tetramethylammonium hydroxide or tetramethylammonium acetate [21] is also a viable way of derivatizing polymers. However, products of the reaction of (meth)acrylic acid with tetramethyl ammonium hydroxide are methylacrylate and methylmethacrylate, which are also common monomers encountered in acrylic polymers.…”
