A process for producing 1-hexene and isobutylene high purity from raffinate-1 which comprises: (a) introducing raffinate-1 and a C 5-6 olefin recycle stream into an MTBE reactor and reacting the isobutylene in the raffinate-1 with methanol to produce MTBE, raffinate-2 and recycled C 5-6 olefins, (b) converting the MTBE to produce high purity isobutylene, (c) separating the recycled C 6 olefins from the recycled C 5 olefins and raffinate-2, (d) producing 1-hexene by separating it from other C 6 olefins, (e) introducing raffinate-2 and the recycled C 5 olefins to a hydroformylation reactor and reacting them with CO and H2 to produce C 5-6 alcohols, and (f) dehydrating the C 5-6 alcohols to produce C 5-6 olefins which are recycled to the MTBE reactor. |
