In the "Steam-digestion process" with or without catalyst for the preparation of furfural from pentosan-containing substances, the average yield obtained is not beyond 10% of the raw material, and it is only about 50% of the theoretical value. As the low yield might be due to the destruction by the secondary reaction-polymerization or other possible reaction in some parts of furfural formed, -the authors attempted to remove the furfural from the reaction zone as soon as it was formed.By such a way-provisionally called "Flash-dehydration process"-xylose in a concentration of 1% solution with 3〜4 N HCl and at 180〜190℃ could be decomposed to furfural as much as 90% of the theoretical yield.Moreover, it has been ascertained that H_2SO_4,a usual catalyst, is unapplicable to this process.
