| Hazard Information | Back Directory | [Description]
Glyoxylic acid monohydrate is a versatile chemical used in various pharmaceuticals, agrochemicals, and cosmetics industries. It is commonly used as an intermediate in producing chemicals like vanillin, amino acids, and herbicides. It should be stored in a cool, dry place away from oxidizing agents and sources of ignition. Glyoxylic acid monohydrate may cause severe skin burns and eye damage, so it is essential to follow proper safety guidelines when handling it. The environmental impact of this product is minimal if it is disposed of according to local regulations. | [Chemical Properties]
white to light yellow crystalline powder or chunks | [Uses]
Occurs in unripe fruit and in young green leaves; has also been found in very young sugar beets. | [Synthesis]
Using maleic anhydride as a raw material, a 20-40% maleic acid solution is obtained by hydrolysis. Ozone is introduced in series at 15-25°C for oxidation, with a molar ratio of ozone to maleic acid of approximately 1.2-1.25:1. The reaction solution is then subjected to vacuum distillation to recover formic acid and water, yielding an 80% glyoxylic acid solution. Finally, granular white glyoxylic acid monohydrate is obtained by crystallization. | [storage]
Store at -20°C |
