PROCESS FOR THE PURIFICATION OF ACETONE FROM THE KETONIZATION OF ACETIC ACID |
| 摘要 |
A method for purification of acetone including the steps of: a) feeding a crude product mixture comprising acetone, water, an impurity to a distillation column; b) withdrawing a liquid side draw stream from the distillation column; c) separating the side draw stream into a water layer and an organic layer, and returning the water layer to the distillation column; and d) recovering from the distillation column: (i) a lower boiling fraction comprising a purified acetone, relative to the crude product mixture and (ii) a higher boiling fraction comprising a major amount of the water. |
