Product 1

HCID 7406Cumene

Procedure

A similar process is described in EP 0371738 wherein the iso-propanol obtained from the hydrogenation step is directly used as alkylation agent in the alkylation of benzene to obtain cumene. The hydrogenation of acetone described in that reference is also similar using Raney nickel in presence of water whereby acetone conversion is only 99% and the Iso-propanol yield is 98.7%.
