GAS-CHROMATOGRAPHIC MASS-SPECTROMETRIC, HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC UV AND GAS CHROMATE GRAPHIC-FOURIER TRANSFORM IR RESPONSES TO AN INDUSTRIAL MIXTURE OF DIISOPROPYLNAPHTHALENES

GC and HPLC parameters and mass spectrometric, ultraviolet and infrare d responses of the diisopropylnaphthalne isomers are reported in order to allow their analytical determination. The interest in these compou nds, widely used in the manufacture of special paper, is linked to the ir appearance as environmental and food pollutants due to recycling an d waste processes.
