Procedure

Isolation of D-mannaric acid as its disodium salt. Prior to titration with sodium hydroxide the solution was stirred at 60° C. for approximately 45 min to promote equilibration between D-mannaric acid acid and lactone species. The isolation procedure was then followed as in Example 1 to give crude mannaric acid disodium salt: 144.4 grams (92% based on pure disodium D-mannarate).
