Procedure

When benzene is alkylated with butenes, e.g., n-butene, to produce butylbenzene, e.g. sec-butylbenzene, the reaction may also take place under at least partially liquid phase conditions including a temperature of up to about 250° C., preferably up to about 150° C., e.g., from about 10° C. to about 125° C.; a pressure of about 25,000 kPa-a or less, e.g., from about 100 kPa-a to about 3,000 kPa-a; a weight hourly space velocity (WHSV) based on butenes 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 butenes in the alkylation reactor of from about 0.5:1 to about 30:1 molar, more preferably from about 1:1 to about 10:1 molar.
