Zusammenfassung:	PROBLEM TO BE SOLVED: To produce anhydrous dioxane by decreasing the number of distillation columns and instruments of the columns to reduce the size of a distillation apparatus, the energy consumption and the cost of the distillation apparatus. SOLUTION: Anhydrous dioxane is produced from hydrated dioxane by distillation using a distillation apparatus provided with the 1st column 21 extending upward from the column bottom, the 2nd column 22 placed adjacent to the 1st column 21 interposing a partition wall 13 and the 3rd column 23 extending downward from its column top to be connected to the 1st and 2nd columns 21, 22. Anhydrous dioxane is produced simply by placing one distillation column 11 and a single set of pumps, instruments, or the like, and, accordingly, the size of the distillation apparatus is reduced to reduce the occupying area of the distillation apparatus.
