✦ Synopsis
The preparation of porous-layer open-tubular columns for gas-liquid chromatography with graphitized thermal carbon black as a solid support and a polar stationary phase is described. The application of these columns is demonstrated by an example.
The reaction products from two oxidation reactions for the production of synthetic citral have been analysed by combined gas chromatography-mass spectrometry. About 30 trace substances resulting from redox reaction and cyclization of the starting materials were found.
