EXAMPLE 2 A 50 wt % solution of D-gluconic acid in water (7.6 g) was spargedwith a stream of dry nitrogen. With continued sparging, the solution washeated to 112 to 118 °C for 1 hour and then 118 to 124 °C for 1 hour.Upon cooling to room temperature, the syrup solidified to a glassy solidthat ¹H and ¹³C NMR indicated to be a 2:1 mixture of D-glucono-1,4-lactone and D-glucono-1,5-lactone.
