Furfural production from xylose and bamboo powder over proton-exchanged reference clays of The Clay Science Society Japan (JCSS-3101, JCSS-3102), and a commercially available clay (K10) in water–toluene biphasic solvent was studied. The three JCSS-3101, JCSS-3102, and K10 catalysts were active for the dehydration of xylose to furfural. The activities of JCSS-3101 and JCSS-3102 were lower than that of K10. Proton-exchanging treatment enhanced the furfural yields for the three JCSS-3101, JCSS-3102, and K10 catalysts. The dehydration behaviors were almost the same and 55% yields were obtained over the three proton-exchanged clays water–toluene biphasic solvent at 413 K for 24 h.
