P216 高温高圧水中におけるグルコース反応に及ぼす金属酸化物の影響

The effect of TiO_2 and ZrO_2 on glucose reactions in hot-compressed water was examined by a batch type reactor. Anatase TiO_2 (a-TiO_2) was found to be an acid catalyst that promoted the formation of 5-hydroxymethyl-furaldehyde (HMF), on the other hand, rutile TiO_2 (r-TiO_2) was inactive.. Zirconia (m/c-ZrO_2: monoclic and tetragonal mixture) was a base catalyst to promote the isomerization of glucose. The TPD spectra showed us that the strength of the acidity and basicity is of importance on the glucose reaction
