Latest Patents
Okamoto's latest patents focus on the process for producing adamantanols. One patent describes a method for efficiently separating and recovering a ruthenium compound used as a catalyst in the production of adamantanols. This process involves hydroxylating an adamantane compound in the presence of a ruthenium compound and a salt of hypochlorous acid within a water/organic solvent two-phase system. The hydroxylation product liquid is treated with an oxidizing agent to extract the ruthenium compound into the organic phase, which is then separated and recovered. Alternatively, the ruthenium compound can be back-extracted into the aqueous phase by adding an aqueous alkali solution to the organic phase, allowing for its recovery.
Another patent outlines a method for producing adamantanols with high selectivity and yields. This process utilizes a specific two-phase solvent system of water and an organic solvent, along with a ruthenium compound and hypochlorous acid or its salt. The addition of a specific alcohol to the reaction liquid facilitates the extraction of adamantanediols, while the ruthenium compound is treated with alkali to transfer it into the water phase, aiding in its recovery.
