Physical and Chemical Properties
Metaldehyde is a highly flammable compound that ignites giving off irritating fumes. It causes irritation of eyes and skin, and also proven to be toxic when ingested. The physical properties of metaldehyde include:
|Appearance||White-colored crystalline solid|
|Molar mass||176.212 g/mol|
|Melting point||246 °C|
|Boiling point||Sublimes at 110 to 120 °C|
|Solubility||Insoluble in water, acetone, acetic acid, and carbon disulfide. Soluble in toluene at 530 mg/L at 20 °C, and in methanol 1730 mg/L at 20 °C|
Depolymerization occurs slowly on heating, however, the process rapidly increases above 80oC. Above 80o C it beings to depolymerize to acetaldehyde, the process completes above 200o C.
Heat of Combustion
The heat of combustion of metaldehyde is 3370 kJ/mol.
Manufacturers of metaldehyde
The increasing demand for high-value horticulture crops has offered growth opportunities for metaldehyde in emerging countries of Asia and South America. Furthermore, the on-going COVID-19 pandemic has hit the demand/supply of metaldehyde along with other chemicals. Except the medical supplies and other pharmaceutical products, the production of a wide range of chemicals were greatly impacted. But this trend will soon change; with the pandemic slowly being in control, the chemical industry will soon function at full swing. By 2023, the global metaldehyde market is expected to reach the previously estimated $727.8 million.
