D-arabino-2-Hexulosonic acid

C6H10O7

收率 5.71%

PROCEDURE

实验过程

The catalyst Pt/Pb/C with Pt/Pb ratio of 5/1.5 is used. The D-glucose solution (5% d.s.) is heated at 55° C., pH is brought to 8 by adding sodium carbonate and the procedure of example 1 is followed. Already in 28 minutes equimolar amounts of alkali are consumed and only 5.71% 2-keto-D-gluconic acid is formed.
