摘要：
A method for the separation of isobutene from a mixture comprising n-butene and isobutene comprising feeding a C.sub.4 stream containing n-butene and isobutene to a distillation column reactor into a feed zone contacting the stream with fixed bed acidic cation exchange resin to form diisobutene which passes to the bottom of the column, said n-butene being removed overhead. The reaction and distillation occur concurrently.
