| titleOfInvention | Process for recovery of cumene hydroperoxide decomposition products by distillation |
| abstract | Products from the decomposition of cuniene hydroperoxide (CHP) are recovered by distillation. The majority of the undesirable by-product acetol (hydroxyacetone) is removed from the phenol stream by distillation wherein the majority of the acetol is carried with an overheads stream comprising acetone, cumene and alphamethylstyrene (AMS). Acetol is subsequently separated from acetone by distillation wherein acetone is taken as an overheads stream and acetol remains with a bottoms stream comprising cumene, AMS and phenol. The acetol, along with residual phenol, is extracted from the cumene and AMS by counter-current washing with an aqueous alkali metal hydroxide. The phenol stream is then distilled to separate phenol from cumene, alphamethylstyrene and higher boiling compounds. The phenol, containing only a small amount of acetol, can then be treated to remove methylbenzofuran by treatment with an acidic resin or solid superacid catalyst without formation of significant amounts of additional methylbenzofuran. |
