The Use and Industry Development of Glyoxylic Acid
Glyoxylic acid is produced through the catalytic oxidation reaction of glyoxal, and is an organic synthesis intermediate with dual characteristics of aldehyde and acid. In the pharmaceutical industry, glyoxylic acid is mainly used to synthesize amoxicillin and allantoin; in the perfume industry, glyoxylic acid can be used to produce vanillin; in agriculture, it can be used to produce chelated fertilizers, etc. Glyoxylic acid has a wide range of applications, and its market demand potential is great.
Organic synthesis intermediates are not only downstream products of basic raw materials in the chemical industry, but also raw materials for fine chemical products. Therefore, the development of the fine chemical industry is closely related to the development of the glyoxylic acid industry. Glyoxylic acid has the largest application in the pharmaceutical industry, and China is the world’s largest producer and exporter of APIs. The demand for glyoxylic acid products in the global pharmaceutical industry is conducive to driving the development of the glyoxylic acid industry.
Preparation of Allantoin from Glyoxylic Acid
Allantoin is prepared from glyoxylic acid and urea. The downstream products of allantoin include alcloxa, aldioxa, diazolidinyl urea, polygalactobionic acid and allantoin’s salicylic acid, ascorbic acid, glycine and other complexes . In medicine, allantoin can be used directly or as an additive; in light chemical industry, allantoin can be used as an additive for cosmetics; in agriculture, allantoin can be used as a regulator to regulate plant growth. In view of the wide application of allantoin in various industries, its development prospect is good. However, due to the high price of allantoin, its application in agriculture is limited. With the development of the glyoxylic acid industry, the consumption of allantoin will also increase significantly.
