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. (482° F.), e.g., a temperature up to about 150° C. (300° F.), e.g., a temperature from about 10° C. (50° F.) to about 125° C. (257° F.); a pressure of about 250 atmospheres or less, e.g., a pressure from about 1 to about 30 atmospheres; and an aromatic hydrocarbon weight hourly space velocity (WHSV) of from about 5 hr31 1 to about 250 hr−1, preferably from 5 hr−1 to 50 hr−1.
