Versuchsvorschrift

It is shown in Examples 7 to 9 that starting from D-glucose it is preferable to start at higher pH to prepare the intermediate, D-gluconic acid, and after equimolar consumption of alkali (sodium hydroxide, potassium hydroxide, sodium carbonate, etc.) a pH drop to 5.0 or below 5.0 is allowed, to obtain high yields of 2-keto-D-gluconic acid.
