Malonic acid, also known as malic acid, is an organic acid with the chemical formula HOOCCH2COOH. It has the properties of being soluble in water, alcohol, ether, acetone and pyridine. It exists in the form of calcium salt in beetroot. The scale deposited in the tank is calcium malonate. Malonic acid is a colorless flaky crystal with a melting point of 135.6 °C, decomposition at 140 °C, and a density of 1.619 g/cm3 (16 °C).

                  Mainly used in pharmaceutical intermediates, also used in spices, adhesives, resin additives, electroplating polishing agents, etc.; used as a complexing agent, also used in the preparation of barbiturate salts, etc.; malonic acid is a fungicide rice blast spirit It is also the intermediate of plant growth regulator indigo ester. ; Malonic acid and its esters are mainly used in spices, adhesives, resin additives, pharmaceutical intermediates, electroplating polishing agents, explosion control agents, thermal welding flux additives, etc. In the pharmaceutical industry, it is used to produce luminal, barbiturates, vitamin B1, vitamin B2, vitamin B6, phenylbutazone, amino acids, etc. Malonic acid is used as an aluminum surface treatment agent. Since only water and carbon dioxide are generated when heated and decomposed, there is no pollution problem. In this respect, compared with acid-type treatment agents such as formic acid used in the past, it has a great advantage. ;Mainly used in pharmaceutical intermediates, also used in spices, adhesives, resin additives, electroplating polishing agents, etc.; used in the production of barbiturates and other drugs, etc.;
