Technology

A High-Yield process to produce High-Purity Phenol and Acetone from Cumene with optional Byproduct Recovery of alpha Methylstyrene (AMS) and Acetophenone (AP). Cumene is oxidized with Air at High Efficiency (+95%) to produce Cumene Hydroperoxide (CHP), which is concentrated and cleaved under High-Yield conditions (+99%) to Phenol and Acetone in the presence of an Acid Catalyst. The Cleavage Mixture is neutralized and fractionated to produce High-Purity products. AMS is hydrogenated to Cumene and recycled to Oxidation or optionally recovered as a pure Byproduct. With AMS Hydrogenation, 1.31 Tons of Cumene will produce 1 Ton of Phenol and 0.616 Tons of Acetone.
