Process for obtaining at least one tertiary olefin by decomposition of the corresponding ether in the presence of a polyarylsilsesquioxane-type catalyst grafted on to an inorganic support

摘要

Process for obtaining a very pure tertiary olefin, for example isobutene, by decomposition of the corresponding ether, for example methyl tert-butyl ether, in the presence of a catalyst of polyarylsilsesquioxane type containing at least one sulphonic (sulpho) group grafted on to an inorganic support, preferably an inorganic oxide such as silica.
