Abstract
Dialyzable fractions of brown polymers synthesized in amino-carbonyl interaction of D-lactose with p-toluidine under condition of acid catalysis in aqueous-ethanolic media was studied by UV-Vis spectrophotometry. To study of the fraction’s compositions and their dialysis dynamics two parallel series spectra of dialysates were measured. It is obtained that non-nitrogenous derivatives in dialyzable fractions are presented as weakly colored products with furan structural fragments, the main nitrogenous component is p-toluidine eliminated by the Amadori rearrangement product’s degradation.
