Procedure
Isopropanol 42 is fed to a cumene process alkylation unit 50 for use as a benzene alkylating material. Fresh propylene 55 may be needed to supplement the isopropanol 42 as the C3 alkylating agent. Byproduct water 54 and cumene product 52 are produced. The cumene stream 52 from alkylation system 50 is mixed with cumene stream 45 from stage 40, and the combined stream 57 is sent to oxidation stage 60, where the cumene is reacted with oxygen in air feed stream 64 to form cumene hydroperoxide stream 62 for feeding to cleavage reactor 10. Stream 62 will typically include about 5-20% of unoxidized cumene plus various impurities and byproducts as discussed above.
