ABSTRACT:
The present invention provides a process for the ethylation of detergent-range olefins to produce higher molecular weight olefins which comprises reacting ethylene with a detergent-range olefin in the presence of a catalyst comprising an alumina having a sodium content per unit surface area of less than about 3.times.10.sup.-5 g/m.sup.2.
