CAS Nr. 298-07-7 se numește Di-(2-ethylhexyl)acid fosforic, este un compus organofosforic care face parte dintr-o clasă de derivați ai acidului fosforic. Este utilizat pe scară largă în diverse aplicații industriale datorită proprietăților sale ca solvent și extractant.
CAS Nr. 298-07-7, the Industrial Benchmark Acidic Organophosphorus Extractant for Metal Purification
CAS Nr. 298-07-7 (chemical names include Bis(2-ethylhexyl) fosfat, De-(2-ethylhexyl) acid fosforic, or more commonly P204 / D2EHPA) is an acidic organophosphorus liquid-liquid solvent extraction (S X) reagent. It stands as the backbone solvent in global non-ferrous hydrometallurgy, renowned for its highly tunable affinity for multivalent metal cations under controlled acidic pH isotherms.
Whether processing end-of-life lithium-ion battery black mass or refining critical rare earth elements (REEs), CAS 298-07-7 acts as a highly selective chelating matrix, providing industrial plants with predictable equilibrium kinetics and robust physical phase disengagement.
