ABSTRACT:
Aromatic hydrocarbons are reacted with olefins using hydrogen fluoride as a catalyst in a process having two reaction zones and settling zones in sequence. The initial admixture of the aromatic hydrocarbons, olefins and catalyst is effected by passing all three materials directly into a centrifugal pump utilized to recirculate liquid hydrogen fluoride from a settling zone. The pump forms the first reaction zone.
