摘要： Catalytic composites of the reaction product of a metal halide having Friedel-Crafts activity with the bound surface hydroxyl group of inorganic oxides and containing a zerovalent metal with hydrogenation activity, often are effective catalysts in motor fuel alkylation which, however, undergo rapid deactivation. Deactivated catalysts are readily regenerable by treating the composite from which alkylate feedstock has been removed with hydrogen at temperatures in the range of 10 to 300.degree. C. Multiple regenerations are possible without appreciable activity loss.

摘要： A method for separating leucine from a mixture of amino acids containing at least leucine and isoleucine, which comprises subjecting an aqueous solution of a mixture of amino acids to centrifugal force, and forcing by the application of pressure a water-saturated organic solvent immiscible with water to pass through the aqueous solution against the centrifugal force, to selectively extract leucine in said water-saturated organic solvent.
