Summary:For the production of a diene a process in three stages comprises a stage a) for decomposition of at least one tertiary alkyl ether in a mixture that contains at least one tertiary olefin, at least one alcohol and at least one residual ether, in the presence of a catalyst that comprises at least one mineral solid that is grafted by at least one organic group such as alkyl sulfonic acid, sulfonic aryl and/or sulfonic alkylaryl, a stage b) for purification of the olefin that is obtained in stage a), and a stage c) for oxidizing dehydrogenation of the tertiary olefin that is obtained in stage b) in the presence of a catalyst under conditions for obtaining a diene.
