INTRODUCTION
Pyruvic acid is a yellowish liquid with vinegar odor. Anatomically, it participates in biological synthesis and metabolic processes of carbohydrates, amino acids, and lipids. Its reactivity is attributed to the presence of two carbonyl groups adjacent to each other and thus the chemical is employed in many synthesis processes leading a variety of end-uses.
Manufacture
The acid is manufactured by ozonolysis of natural rubber (levulinic acid as by-product) or by DL-lactic acid oxidation or by distillation of tartaric acid over KHSO4.
