Benzene → Cumene

Participants

Reaction Steps

When benzene is alkylated with propylene to produce cumene, the reaction may also take place under liquid phase conditions including a temperature of less than about 200° C., preferably from about 100 to 200° C.; a pressure of about 450 psig (3102 kPa) or less, e.g., from about 250 psig (1724 kPa) to about 600 psig (4137 kPa) or less; or about 450 psig (3102 kPa); a weight hourly space velocity (WHSV) based on propylene alkylating agent of from about 0.1 hr−1 to about 25 hr−1, preferably from about 0.3 hr−1 to about 5 hr−1; and a molar ratio of benzene to propylene in the alkylation reactor of from about 0.5:1 to about 50:1 molar, more preferably from about 1:1 to about 20:1 molar.
