Benzene → Cumene

Participants

Reaction Steps

The experimental setup of Example 1 is employed in the alkylation of benzene with propylene to form cumene, with the exception of the following changes. The pretreatment bed containes 20 g mordenite catalyst instead of 10 g. Benzene flow over the guard bed is 40 hr−1. Benzene flow over the alkylation catalyst is 800 hr−1. Propylene flow into the alkylation reactor is 12 hr−1. Combined propylene and benzene flow through the alkylation reactor is 812 hr−1. Benzene/propylene molar ratio is 66.7. Both the pretreatment zone and alkylation zone are started at 150° C. FIG. 2 shows the effect of varying the temperatures of the pretreatment zone and the alkylation reactor on the yield of cumene.
