Summary

The UV spectra in a neutral and an alkaline medium and the δε spectra have been obtained for a number of Hibbert ketones: vanillin, guaiacylacetone, vanilloyl methyl ketone, α-hydroxypropiovanillone, α-ethoxypropiovanillone, α-ethoxypropiosyringone, syringylacetone, coniferyl, syringyl, and sinapic aldehydes, and p-hydroxybenzaldehyde, and also for samples of oak and pine ethanol lignins. Characteristic minima and maxima that can be used for identification have been found in the above-mentioned spectra.
