For a comparison, the same reaction vessel as above the inside of which was under atmospheric pressure was placed in water at 75° C., and the aqueous solutions of diacetone-L-sorbose, nickel chloride and sodium hypochlorite were fed into the reaction vessel in the same manner as above. The reaction temperature was found to rise temporarily to 85°-90° C., and then lowered to 75 ° C. The reaction concluded in 60 minutes. The resultant reaction mixture was worked up in the same manner as above, to provide diacetone-2-keto-L-gulonic acid.
