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., e.g., up to about 150° C., e.g., from about 10° C. to about 125° C.; a pressure of about 250 atmospheres or less, e.g., from about 1 to about 30 atmospheres; and an aromatic hydrocarbon weight hourly space velocity (WHSV) of from about 5 hr-1 to about 250 hr-1, from 5 hr-1 to about 50 hr-1. An example of a combination of reaction conditions includes a temperature of from about 10° C. to 150° C, a pressure of from about 1 to about 30 atmospheres, and a WHSV of from about 5 to about 50 hr-. Another example of a combination of reaction conditions includes a temperature of from about 10° C. to 250° C., a pressure of from about 1 to about 250 atmospheres, and a WHSV of from about 5 to about 250 hr-.
