The extraction of vanillin (4-hydroxy-3-methoxybenzaldehyde) from water medium with octylamine solution in heptane was studied. The distribution ratios were found to increase with the octylamine concentration and to attain values up to 600. The slope of the logarithmic dependence of the distribution ratios versus octylamine concentration is equal to 1.62 + 0.14. In the organic phase, the vanillin molecule reacts with octylamine by both phenolic and carbonyl groups forming the Schiff base RN5 5CH-Ar-OH . . . NH 2 R. The structure of the compounds formed was confirmed by 1 H NMR spectroscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
