Method for producing furfural, and method for producing furan |
| abstract |
A problem is to provide an industrially advantageous method in which in purifying a furfural composition, the formation of a solid matter which have been unable to be controlled so far is stably reduced, and furfural is purified with high efficiency wherein the problem has been solved by a method for producing furfural including distilling a composition containing furfural by a distillation column to obtain furfural, wherein a concentration of a furfural dimer in a column bottom liquid of the distillation column is controlled to 20 ppm by mass to 5,000 ppm by mass. |
