Phosphorous Compounds

Phosphine compounds refer to compounds containing phosphine (P) in their molecules. Phosphine is an element in the 15th group of the periodic table and has relatively active chemical properties. Common phosphine compounds include phosphonic acid (H₃PO₃), phosphine salts (such as phosphates) and organic phosphine compounds. Applications of phosphine compounds: Pesticides and insecticides: Some organic phosphine compounds are common insecticides, such as parathion and dichlorvos. These compounds work by inhibiting the activity of esterases in the nervous system of insects. Catalysts: Phosphine compounds are often used as catalysts or catalyst ligands in organic synthesis reactions. For example, phosphine compounds act as ligands in certain metal-catalyzed reactions and can adjust the selectivity and reaction rate of the catalytic process. Additives: For example, in the lubricating oil, plastics, and rubber industries, phosphonate compounds are used as additives to improve the performance of products and extend their service life. Photocatalysis and optoelectronic materials: Some phosphine compounds are used as functional additives or components in optoelectronic materials and catalysts, and are used in the fields of photocatalysis, solar cells, etc. Water treatment: Phosphonates and other phosphine compounds can be used as scale inhibitors in water treatment processes to avoid corrosion and deposit formation on metal surfaces.
