Purification method of cyclic formal |
| abstract |
(57) [Summary] [Object] To provide a purification method for efficiently removing water from a cyclic formal that is difficult to separate from water to obtain a highly pure cyclic formal having a very low water content. A method for purifying cyclic formal, characterized in that, when a mixture containing cyclic formal and water is supplied to a distillation column to purify the cyclic formal, distillation is performed while supplying n-hexane to the distillation column. |
