Pd—Bi/C催化剂选择性氧化葡萄糖醛基的研究

Studies on the Palladium-Bismuth/carbon Catalyst Selectively Oxidizes only the Aldehyde Group of Glucose

本文研制了一种氧化葡萄糖醛基成葡萄糖酸盐的高选择性催化剂—Pd-Bi/c双金属负载型催化剂。在本文的制备条件下,该催化剂能在常压低温下使葡萄糖醛基氧化的选择性达到了97.9％,且产率达到90％以上。催化剂可重复使用10次以上。

In this paper a Palladium-Bismuth/Carbon Catalyst has been prepared by allowing an active carbon containing a Previously adsorbed Bismuth compound to support a Palladium compound thereon and reducing the same · In the oxidation reaction of glucose exthemely high activity and selectivity are directly related to the bimetallic atoms grouP compound, and the selectivity of the aldehyde group of Glucose was 97.9 % and the yield of sodium gluconate was over 90%.
