Abstract

The effect of phenolic compounds on hydrothermal oxidation of cellulose was studied using a batch reactor at 300 °C with H2O2 as oxidant. Intermediate products, as well as the yields of acetic acid produced in the oxidation of cellulose, phenolic compounds, and cellulose-phenolic compound mixtures were examined. Phenolic compounds used were phenol, 1,4-benzenediol, 2-methoxy-4-methylphenol, and 2,6-di-tert-butyl-4-methylphenol. In the case of oxidation of cellulose-phenolic compound mixtures, (1) formic acid, a basic oxidation product from carbohydrates, decreased considerably, (2) 5-hydroxymethyl-2-furaldehyde and 2-furaldehyde, acid-catalyzed dehydration products from carbohydrates, appeared, and (3) the yield of acetic acid increased compared to that in the oxidation of cellulose. From these results, phenolic compounds seem to inhibit the oxidation of cellulose under hydrothermal conditions. The inhibition of the oxidation of cellulose by phenolic compounds seems to be related closer to the stability of phenolic compounds under oxidation conditions rather than the ease to remove phenolic hydrogen on the OH group.
