Abstract

Keto acids or esters, or precursors thereof, e.g., acetone dicarboxylate diesters, are prepared by reacting an alpha -hydroxy acid, e.g. citric acid, or a derivative thereof, with an anhydrous inorganic acid or carboxylic acid anhydride in the presence of an inert, water-immiscible organic solvent. Processing difficulties can be reduced when the keto acids or esters are prepared in a reaction medium containing such an organic solvent.
