Glycollic Acid

The chemical effects following the carbon photoneutron reaction in calcium carbonate and sodium bicarbonate have been studied. After solution of the irradiated crystals, C11 was found to be present in the forms of carbonate, carbon monoxide, formic acid, oxalic acid, glyoxylic acid, and glycollic acid. The relative amounts of C11 appearing in each form agreed closely with those found previously for irradiations of solid sodium carbonate.

Hydrous Zirconium

Patients suffering from primary hyperoxaluria show elevated plasma concentrations of oxalic acid and glyoxylic acid. The in vitro adsorption of these compounds onto activated charcoal, a series of neutral and ion exchange resins and onto hydrous zirconium oxide has been investigated. Hydrous zirconium oxide was the most effective sorbent studied for the removal of both oxalic acid and glyoxylic acid. In batch experiments, the zirconium oxide was capable of binding 5.5 μ mol oxalic acid and 8 μ mol glyoxylic acid per gram sorbent using 0.5 gram sorbent and 50 ml of solutions with initial concentrations of 100 μ mol. L−1 and an ionic composition resembling that of plasma. Recirculation of 2 L of the same solutions through 12 gram of a mixture of hydrous zirconium oxide and alumina for 6 hours at a flow rate of 12 ml.min−1, resulted in a final concentration of 70 μ mol. L−1 of oxalic acid and 50 μ mol. L−/ of glyoxylic acid.

The starch was oxidized with 5.5 base molar equivalents of 0.43 M calcium hypochlorite kept near pH 12 and 20°. The rate of oxidation was consistent with the occurrence of two first-order reactions differing in rate by a factor of 10, the more rapid of which consumed about 4 moles of hypochlorite for each C6H10O5 unit actually oxidized. Oxalic acid (0.2 mole) and perhaps carbonic acid [Formula: see text] were formed directly, but it was necessary to hydrolyze the product in order to liberate D-glucose (0.4 mole), glyoxylic acid (0.03 mole), D-erythronic acid (0.11 mole), mesotartaric acid (0.02 mole), D-tartaric acid (0.02 mole), L-tartaric acid (0.01 mole), D-glucuronic acid (0.004 mole), and probably tartronic acid [Formula: see text].
