About:
glyoxylicacid (English), also known as formylformic acid, hydrated glyoxylicacid, oxyacetic acid, chemical formula C2H203, is the simplest aldehyde acid, present in unripe fruits, green leaves and sugar beets. Crystallized from water is monoclinic crystal system (containing 1/2 crystal water). Relative molecular weight 70.04. Melting point 98℃. Has an unpleasant taste, is a strong corrosive acid, easily deliqued, exposed to air, can form a slurry. Slightly soluble in ethanol, ether, benzene, can be arbitrarily dissolved in water, aqueous solution in the air is very stable, does not deteriorate. It exists as a hydrated form in an aqueous solution. Can react with most metals except stainless steel. Both acid and aldehyde properties. It can be added with sodium bisulfite or hydrocyanic acid, with hydroxylamine or phenylhydrazine to produce oxime or hydrazone, can occur silver mirror reaction, can occur conicharro reaction, can also produce carboxylate and esters.

Purpose:
Glyoxylic acid is the simplest keto acid (aldehyde acid), both acid and aldehyde properties, used as varnish raw materials, fragrances, medicines, dyes, plastics and household chemicals intermediates. It can be used to produce oral penicillin vanillin, ethyl vanillin, and allantoin (see 01320). Allantoin is an anti-ulcer drug, but also some pharmaceutical products, daily chemical intermediates, further processing can be made into a microefficient liquid fertilizer.

Production method:
1. Oxalate electrolysis method oxalic acid aqueous solution is electrolytically reduced to produce glyoxylic acid dilute solution, and then gradually enriched by evaporation, concentration, freezing, filtration, and finally qualified product packaging.
2. Glyoxal oxidation method Glyoxal is oxidized by air or oxygen under the action of catalyst to produce glyoxalic acid, and then the finished product is refined and purified. In addition, dichloroacetic acid is condensed with sodium methanol to obtain sodium dimethoxyacetate, and then hydrolyzed with hydrochloric acid to produce glyoxylic acid.
