A process for the production of C8 alkenes with high selectivities to 2,4,4-trimethylpentene by the oligomerization of isobutene and/or n-butene at lower temperatures is disclosed. Higher proportions of heavy paraffins mixed with the butene feed in the oligomerization zone improve the selectivity to 2,4,4-trimethylpentene along with better selectivity to octene and lower selectivity to dodecene. Additionally, we have found that n-butene codimerizes with isobutene selectively to 2,4,4-trimethylpentene.
