Pyroracemic acid, which is called also pyruvic acid, may be prepared by methods which furnish evidence in favor of the structure assigned to it. It is formed, for example, by oxidizing lactic acid —... [Pg.303]

Pyroracemic acid melts at 9° and boils at 165°. It shows the reactions of both acids and ketones. It forms salts, esters, an oxime, and an addition-product with hydrocyanic acid. When heated with dilute sulphuric acid at 150°, it decomposes according to the following equation —... [Pg.303]
