EPA chemical information: Phosphonicacid, (2-ethylhexyl)-, mono(2-ethylhexyl)ester
Properties: This product is yellowish transparent oily liquid, soluble in organic solvents such as alcohol, benzene, ketone, etc., insoluble in water, ignition point 228℃.
Uses: This product is an acidic phosphorus extractant, widely used in the extraction and separation of non-ferrous metals and rare earths.
Production method: Phosphorus trichloride reacts with 2-ethyl hexanol to form bis(2-ethyl hexano) phosphite, and then condenses with monochloro (2-ethyl hexan) in the presence of sodium ethoxide to obtain 2- Ethylhexyl Chemicalbook phosphonic acid bis(2-ethylhexyl) ester. It is then hydrolyzed with ethanolamine to produce 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester. (Kg/ton) Phosphorus trichloride 4422-ethylhexanol 1224.
