Process for the preparation of 2-keto-2-gulonic acid esters

Acid-catalyzed esterification of 2-keto-L-gulonic acid or diacetone-2-keto-L-gulonic acid with an alcohol to produce a 2-keto-L-gulonic acid alkyl ester is carried out in a liquid film on a hot surface with simultaneous water removal. The esters have 1-10C and are produced from the corresponding 1-1...
