ABSTRACT:
Conversions of over 80 mole % of n-butenes to oligomers can be obtained with less than 15 mole % C.sub.12 or higher oligomers by passing a predominantly C.sub.4 stream containing at least 40 mole % n-butenes through an acidic cation exchange resin at LHSV 2 to 5 at temperatures in the range of 80.degree. C. to 130.degree. C., in liquid phase by cofeeding from 1 to 5 weight %, based on the C.sub.4 stream, of methyl tertiary butyl ether, secondary butyl methyl ether, toluene or mixtures thereof.
