A process for the purification of raw acetone deriving from processes for the production of phenol acetone, impurity mainly due to cumene, water, aldehydes and methanol, the steps of:

Process for the purification of acetone

A stream of raw phenol, coming from the acidic cracking of cumene hydroperoxide, is purified by a process of extractive distillation carried out in the presence of acetophenone.

Process for purifying phenol

The disposal of chlorinated pitches is carried out by a process which employs two treatments with an alcohol, which are carried out in cascade. Such treatments cause the precipitation of the suspended matter to take place. This is then caused to settle, and is separated and pyrolized, while the supernatant is distilled in order to separate the alcohol, which is recycled back to the process, from other organic components, which are sent to further uses.
