Die Erfindung betrifft ein Verfahren zur Herstellung von in organischen Lösungsmitteln dispergierbaren Metalloxiden bzw. Metallaquoxiden, insbesondere Tonerdehydraten, und nach diesem Verfahren herstellbare mit organischen Sulfonsäuren modifizierte Metalloxide bzw. Metallaquoxide. The invention relates to a method for the production of metal oxides or metal aquo oxides, especially alumina hydrates, dispersibles in organic solvents and to metal oxides or metal aquo oxides produced according to said method and modified with organic sulphonic acid. L'invention concerne un procédé de fabrication d'oxydes métalliques ou d'oxydes métalliques hydratés, en particulier des hydrates d'alumine, dispersibles dans des solvants organiques, ainsi que des oxydes métalliques ou des oxydes métalliques hydratés, modifiés par des acides sulfoniques organiques, fabriqués suivant ce procédé.
