Benzene → Cumene

Participants

Reaction Steps

The present invention is a phenol producing apparatus including a reaction tower for forming cumene by benzene and propylene, an oxidation tower for forming cumene hydroperoxide by oxidizing the cumene at downstream of the reaction tower, a concentration tower for concentrating the cumene hydroperoxide at downstream of the oxidation tower, a disintegration tower for forming coarse phenol and coarse acetone by disintegrating the concentrated cumene hydroperoxide by the acid material at down stream of the concentration tower and each kinds of distillation tower for separating and refining the coarse phenol and the coarse acetone at downstream of the disintegration tower, which is provided with the hydrophilic contaminants removing assembly in at least one portion on the passage between the oxidation tower and the concentration tower, between the disintegration tower and the distillation tower, or on the passage provided for feeding back the excess cumene from the concentration tower to the upstream side of the oxidation tower.
