Method for purifying phenol |
| abstract |
The present invention relates to a process for the preparation of a distillation column comprising feeding a feed comprising phenol, acetone, hydroxyacetone and water to a distillation column at a temperature of from 60 to 95; Separating the feed into a first fraction comprising the acetone and separated into the upper portion of the distillation column and a second fraction containing the phenol and separated into the lower portion of the distillation column; And recovering the first fraction and the second fraction, respectively. |
