<p>A process for the production of propylene from the metathesis of ethylene and 2-butene is disclosed wherein a mixed C<SUB>4</SUB> stream is first treated to enrich and separate the 2-butene from 1-butene and isobutene by isomerization of 1-butene and concurrent fractional distillation of the 2-butene and isobutene to provide the 2-butene feed the metathesis with ethylene. In addition the mixed C<SUB>4</SUB> stream may be treated to remove mercaptans and dienes prior to 2-butene enrichment.</p>
