Procedure

To an 150 l-capacity reaction vessel kept at a reduced pressure of 300 Torr were fed 450 kg of a 33.3% by weight of an aqueous solution of diacetone-L-sorbose, 9 l of a 5% by weight of an aqueous solution of nickel chloride and a 12.5% by weight aqueous solution of sodium hypochlorite in amounts shown in Table 3 concurrently with each other in 1 hour. The reaction started at once, and boiled at 75° C. An amount of about 160 l of water was distilled off as the reaction proceeds, when the reaction concluded. The reaction mixture was worked up in the same manner as in Example 1, to provide diacetone-2-keto-L-gulonic acid.
