Product 1

HCID 7406Cumene

Procedure

When benzene is alkylated with propylene to produce cumene, the reaction may also take place under liquid phase conditions including a temperature of up to about 250° C., for example up to about 150° C., for example from about 10° C. to about 125° C.; a pressure of about 250 atmospheres or less, for example from about 1 to about 30 atmospheres; a molar ratio of the benzene to the propylene of from about 1:1 to about 30:1, for example from about 1:1 to about 10:1, and a feed weight hourly space velocity of from about 5 hr−1 to about 250 hr−1, for example from 5 hr−1 to 50 hr−1, based on benzene feed.
