Abstract
PURPOSE: To obtain the titled compound useful as a synthetic intermediate for a variety of organic compounds, especially medicines or cosmetics, in high purity and yield, by the hydrolysis and purification through distillation of a pyruvic ester at temperatures in a specific range.
CONSTITUTION: An ester of pyruvic acid is hydrolyzed in water preferably in a molar amount of 4 times or more and 10 times or less that of the ester of pyruvic acid, and purified through distillation, at 50W80°C, to give pyruvic acid.
EFFECT: Readily storable and handleable due to the little deterioration because of the high purity.
