Classical industrial production processes employ solid acids,
WebCumene is oxidized in slightly basic conditions in presence of a radical initiator, which removes the tertiary benzylic hydrogen from cumene and hence forms a cumene … WebFeb 25, 2005 · Cumene production Cumene is produced commercially through the alkylation of benzene with propylene over an acid catalyst. Over the years, many different catalysts have been proposed for this alkylation reaction, including boron trifluoride, hydrogen fluoride, aluminum chloride, and phosphoric acid.
WebReaction Kinetics production of cumene (isopro- pylbenzene) involves the reaction of benzene with propylene in a high-temperature, high-pressure gas-phase reactor. C 6 H 6 … WebCumene vapor can be absorbed by the respiratory tract. Sufficiently high levels of exposure to cumene causes central nervous system (CNS) depression leading to death, internal …
WebThe overall yields of cumene for this process are typically 97—98 wt % with transalkylation and 94—96 wt % without transalkylation. Production of a-methylstyrene (AMS) from cumene by dehydrogenation was practiced commercially by Dow until 1977. It is now produced as a by-product in the production of phenol and acetone from cumene. …
