The sequence of product formation and kinetic regularities of vanillin transformation in
propanol-2 medium at different temperatures and duration of the process in a static mode
are investigated. The vanillin conversion products were determined using gas
chromatography-mass-spectrometry method. At a high degree of vanillin conversion
(up to 100 %), a relatively small number of compounds are formed, the main of which
are substituted phenols and their derivatives, such as vanillyl alcohol and its isopropyl
ether, guaiacol, creosol (2-methoxy-4-methylphenol), and homocatechol (3,4-
dihydroxytoluene). A scheme of reci procal transformations of intermediate compounds
is proposed.
