Alkali Fusion-Gas Chromatography

Amino and Imido Groups 3.13.1 Alkali Fusion-Gas Chromatography 

Schleuter and Siggia [131-133] and Frankowski and Siggia [134] used alkali fusion reaction gas chromatography for the analysis of imide monomers and aromatic polyimides, polyamides, and poly(amide-imdes). Samples are hydrolysed with a molten potassium hydroxide reagent at elevated temperatures in a flowing inert atmosphere  

Volatile reaction products are concentrated in a cold trap before separation by gas chromatography. The identification of the amine and/or diamine products aids in the
