Process for the production of a cut rich in tert-amyl alkyl ether free from olefins and of a paraffinic cut rich in N-pentane

摘要

Simultaneous production of a cut rich in a tert-amyl alkyl ether free from olefins and of a paraffinic cut rich in N-pentane. The invention is characterised in that a feed stock based on isopentenes is hydrogenated (1) in conditions which are appropriate for obtaining a distribution of the methylbutenes which is close to thermodynamic equilibrium, and in that the hydrogenation effluent is then processed in an etherification zone (2). <IMAGE>
