Jegorov, J. Tříska, H. Zahradníčková] Summary: Higher aliphatic amines and cyclohexylamine find use on a large scale as inhibitors of corrosion in power stations and in installations for drawing and storing natural gas in underground containers. The determination of active constituents of the inhibitors at the individual technological steps, very important for assessing the efficacy of the anticorosive protection, is complicated by other compounds accompanying the trace amounts of the amines being monitored. This circumstance makes it necessary to use selective methods based on the derivatization of the primary amino group and formation of intensively UV-VIS absorbing or fluorescent derivatives. These demands are met by the detection with ninhydrine [1, 2] or TLC of 2,4-dinitrophenyl-[3,4] or 3,5-dinitrobenzoyl-[5] amine derivatives. We applied a modified derivatization procedure with 1-fluoro-2,4-dinitrobenzene as UV label [6], well known as Sanger's reagent originally developed for the labeling of amino acids and peptides [7]. This reagent forms with amines intensively absorbing N-alkyl-2,4-dinitroaniline derivatives which can be easily separated by TLC. Springer-Verlag, 1990 Jegorov A.
