Abstract
Application of differential spectrophotometry to furfural enables the presence in it of foreign compounds, especially the products of its autoxidation, and also their nature to be established by a spectral comparison of the sample investigated with pure furfural. The special feature of the spectrum is that the position of the characteristic maximum formed in the presence of various substances changes according to the thickness of the layer investigated: λmax=15.9 log l + λ0. The establishment of these properties enables the method to be usedfor the study of different amounts of impurities in furfural by varying the layer thickness. The method is simple in use and possesses a high sensitivity.
