Homovanillic Acid → 2,6-Dimethoxyphenol

Participants

Reaction Steps

As it is shown in Table 1.4, in the case of vanillic acid, homovanillic acid and acetovanillon, average initial concentrations of ca. 60 ppm, ca. 25 ppm and ca. 5 ppm, respectively, were found. After treatment in the reactor, the concentrations of all three species were reduced to a level around or under the detection limit (1-2 ppm) for the analysis. Similar results were obtained for syringic acid, acetosyringon and syringol, for which average initial concentrations of ca. 45 ppm, ca. 28 ppm and ca. 7 ppm, respectively, were found, whereas the concentrations after treatment in the reactor were all around or under the analytical detection limit of 1-2 ppm.
