TOTRINNSPROSESS FOR FREMSTILLING AV ISOBUTYLEN FRA PROPYLEN OG SYNTESEGASS.

摘要

The invention concerns a dual step process for producing isobutylene from propylene and synthesis gas. In the first step propylene is contacted with synthesis gas at elevated temperature in the presence of a catalyst system containing a mixture of monometal compounds M4 (CO)12 and M4 (CO)12 and/or bimetal compound M2M2 (CO)12. The alcohol mixture thus obtained is dehydrated in the second step for producing a product fraction containing isobutylene in plenty.
