Reaction Steps
Except that 200 ml of 0.1 w/v% solution of sodium ascorbate in water-methanol (water/methanol-1/100) was used in place of 200 ml of the solution of sodium hydroxide in methanol in Example 1, a similar treatment to that in Example 1 gave 190 g of ascorbic acid powder of 100 mesh pass. The powder contained about 30 ppm of sodium ascorbate.
