| Abstract: | Summary The UV spectra in a neutral and an alkaline medium and the   spectra have been obtained for a number of Hibbert ketones: vanillin, guaiacylacetone, vanilloyl methyl ketone,  -hydroxypropiovanillone, -ethoxypropiovanillone, -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.Khimiya Prirodnykh Soedinenii, Vol. 3, No. 5, pp. 339–344, 1967 |
