M. Kolb et M. Bahadir, FORMATION OF SCHIFF-BASES WITH ACETONE AS A SOLVENT IN THE DETERMINATION OF ANILINES, Journal of chromatography, 685(1), 1994, pp. 189-194
The formation of Schiff bases, when using acetone as solvent in the de
termination of aniline and substituted basic anilines, was verified by
GC-MS and GC-Fourier transform measurements. These reaction products
are detected as additional peaks in GC, impairing calibration and quan
tification.
