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 from about 100° C. to less than about 200° C.; a pressure from about 100 psig (689 kPa) to about 500 psig (3450 kPa), preferably from about 100 psig (689 kPa) to 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 250 hr−1, preferably from about 1 hr−1 to about 50 hr−1; and a ratio of benzene to propylene in the alkylation reactor of from about 0.5:1 to about 30:1 molar, preferably from about 1:1 to about 10:1 molar.
