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

The previously proposed mechanism for lignin oxidation to vanillin was supported experimentally. This process begins with the formation of a phenoxyl radical and ends with the step of retroaldol cleavage of substituted coniferaldehyde to vanillin. Th

It has been established that in the oxidation of diethyl sulfide by18O2 in CH3C16O2H−H216O solution at 369 K catalyzed by heteropoly acids, sulfoxide and sulfone with 44–54%18O enrichment are formed. The process is accompanied by isotope exchange
