WIPO Patent Application WO/2015/170718
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an industrially advantageous method for purifying a furfural composition with high efficiency while steadily reducing the production of a solid matter which cannot be controlled by the conventional methods. The problem can be solved by a method for producing furfural, which comprises distilling a furfural-containing composition through a distillation column to produce furfural, said method being characterized in that the concentration of a furfural dimer in a column bottom solution in the distillation column is adjusted to 20 to 5000 ppm by mass.
