Benzene → Cumene

참여 물질

반응 단계

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., preferably up to about 150° C., e.g., from about 10 to about 125° C.; a pressure of about 250 atmospheres or less, e.g., from about 1 to about 30 atmospheres; 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 100:1 molar, preferably from about 0.5:1 to about 30:1 molar, more preferably from about 1:1 to about 10:1 molar.
