Reaction Steps
Japanese laid-open application 58-177986 describes a process which includes the addition of ethanol and acetone to the sodium salt of 2-keto-L-gulonic acid, neutralization with hydrochloric acid, separating off the sodium chloride which is precipitated out by filtration and then holding the reaction mixture at temperatures in the range from 25° C. to 75° C., as a result of which L-ascorbic acid is obtained.
