Decomposition of Pyruvic Acid on the Ground-State Potential Energy Surface

Journal of Physical Chemistry A, 2016
A potential energy surface is reported for isomerization and decomposition of gas-phase pyruvic acid (CH3C(O)C(O)OH) in its ground electronic state. Consistent with previous works, the lowest energy pathway for pyruvic acid decomposition is identified as

Hydration and dehydration of pyruvic acid

J. Chem. Soc. B, 1970
The reaction rates and equilibria involved in the hydration and dehydration of pyruvic acid have been investigated by the n.m.r. technique for solutions from pH 6 to hydrochloric acid concentration 4M. Dissociation constants were estimated (from the equilibria and changes in chemical shifts) to be pK 1·5 for the unhydrated acid and pK 3·0 for the ...

The microwave spectrum of pyruvic acid

Chemical Physics Letters, 1973
Abstract The microwave spectrum of pyruvic acid (CH 3 COCOOH) has been investigated between 8 and 40 GHz. The rotational transitions in the vibrational ground state have been assigned. Rotational constants and centrifugal distortion constants have been fitted from all measured transitions up to J = 42.

Photoinduced Oligomerization of Aqueous Pyruvic Acid

The Journal of Physical Chemistry A, 2006
The 320 nm-band photodecarboxylation of aqueous pyruvic acid (PA), a representative of the alpha-oxocarboxylic acids widely found in the atmospheric aerosol, yields 2,3-dimethyltartaric (A) and 2-(3-oxobutan-2-yloxy)-2-hydroxypropanoic (B) acids, rather than 3-hydroxy-2-oxobutanone as previously reported. A and B are identified by liquid chromatography

Polarographic reduction of pyruvic acid

Proceedings of the Indian Academy of Sciences - Section A, 1958
The application of Delahay’s theory of kinetic polarographic currents as applied to the reduction of pyruvic acid has been examined. It is shown that the agreement between Delahay’s theory and the available data is more satisfactory, if one assumes that the current is controlled by the rate of the reaction between pyruvate ion and water molecule ...

Atmospheric reactions of pyruvic acid

Atmospheric Environment (1967), 1983
Abstract The keto acid pyruvic acid, CH3C(O)COOH, photolyses in sunlight with a rate constant of 1.6 × 10−2 min. Comparison of data for pyruvic acid-pure air and pyruvic acid-NOx mixtures indicates negligible (≤5%) removal of pyruvic acid by reaction with the hydroxyl radical.
