  A ruthenium-carrying alumina, which is prepared by suspending alumina in a solution containing trivalent ruthenium and adding a base to the suspension, is provided. This ruthenium-carrying alumina is useful as a catalyst for oxidizing alcohols by contacting the alcohols with molecular oxygen, and can be used for oxidizing the alcohols at a high conversion to produce ketones, aldehydes, carboxylic acids, etc. with good productivity.

  提供了一种携带钌的氧化铝，该氧化铝是通过将氧化铝悬浮在含三价钌的溶液中并向悬浮液中加入碱来制备的。这种携带钌的氧化铝可用作氧化醇的催化剂，通过将醇与分子氧接触，可以将醇氧化为酮、醛、羧酸等，在高转化率下产生良好的产量。
