摘要
A mixture of three model compounds of lignocellulosic biomass, namely glucose, xylose, and guaiacol, was treated in supercritical water to investigate the interactions taking place between the model compounds. All experiments were carried out at 450 °C and 25 MPa, with varying residence times of 5–40 s. The inclusion of guaiacol resulted in high yields of both 5-hydroxymethylfurfural and furfural. In addition, reaction rate constants were determined for the reaction network, and a comparison with literature values indicated that guaiacol addition suppressed radical reactions, thus increasing the yields of products derived from ionic reactions.
