  In the production of hydrogen peroxide, when ketone forms are increased upon conversion from higher alcohol components in organic solvents, such increased levels of ketone forms reduce the water content in a working solution and lead to deterioration of catalytic activity. Moreover, increased levels of ketone forms reduce the solubility of anthrahydroquinone compounds and may cause an obstacle to stable and safe operation in the production of hydrogen peroxide due to crystallization and deposition of the anthrahydroquinone compounds. The object of the present invention is to provide a process in which polar solvent-derived altered substances (ketone forms) in a working solution provided for use in the production of hydrogen peroxide via the anthraquinone process are regenerated into the original alcohol components to thereby improve the production efficiency of hydrogen peroxide. From a working solution which has been used for many years, organic solvent components containing ketone forms are separated by distillation and hydrogenated in the presence of a metal catalyst to regenerate the organic solvent components into the original alcohol components, whereby hydrogen peroxide can be produced more efficiently.

  在过氧化氢的生产过程中，当从有机溶剂中的高级醇成分转化而来的酮形式增加时，这种酮形式含量的增加会降低工作溶液中的含水量，导致催化活性降低。此外，酮形式含量的增加会降低蒽氢醌化合物的溶解度，并可能由于蒽氢醌化合物的结晶和沉积而对过氧化氢生产中的稳定和安全操作造成障碍。 本发明的目的是提供一种工艺，在该工艺中，通过蒽醌工艺生产过氧化氢所用的工作溶液中的极性溶剂衍生的改变物质（酮形式）被再生为原始的醇成分，从而提高过氧化氢的生产效率。 从已使用多年的工作溶液中，通过蒸馏分离出含有酮形式的有机溶剂成分，并在金属催化剂存在下进行氢化，将有机溶剂成分再生为原始醇成分，从而更有效地生产过氧化氢。
