The Industry-Standard Acidic Phosphonate Extractant for Critical Mineral Fractionation
CAS 번호. 14802-03-0 (화학적 이름: 2-에틸 헥실 포스 폰산 모노 -2- 에틸 헥실 에스테르, commonly traded as P507, PC-88A, or HEHEHP) is a high-purity acidic organophosphorus solvent extraction (SX) 시약. Standing alongside its phosphoric counterpart D2EHPA (P204), CAS 14802-03-0 provides a slightly higher pKa value, enabling drastically elevated separation factors for adjacent metal cations that exhibit nearly identical physical-chemical properties.

Crucial Industrial Applications & Extraction Mechanics
1. Advanced Lanthanide Separation (Heavy & Light REE Cascades)
In rare earth hydrometallurgy, splitting adjacent lanthanides is incredibly challenging due to ionic similarities.
P507의 장점: CAS 14802-03-0 yields vastly superior separation factors compared to standard D2EHPA. It facilitates predictable, stable loading and scrubbing behaviors across multi-stage mixer-settler batteries, ensuring that final oxides reach high purity metrics (99.99%).
2. High-Purity Nickel-Cobalt Separation
For lithium-ion battery precursor cathode active material processing, isolating cobalt cleanly away from large background matrixes of nickel is critical.
At a tailored acidic operational window (pH 4.0-5.0), P507 binds selectively with cobalt ions, 수성 라피네이트 흐름에서 니켈이 완전히 거부되게 남겨두기.
3. Rare Metal Scrap & Catalyst Recycling
Extensively deployed in secondary recycling circuits to isolate valuable strategic bypass metals, including indium, 몰리브덴, 바나듐, and specific platinum-group metals out of spent electronics or petrochemical hydrotreating catalysts.
Key Chemical Features:
Low Water Phase Solubility: Highly hydrophobic architecture ensures minimal entrainment loss into processing raffinate solutions, keeping chemical top-up expenses low.
Excellent Stripping Efficiency: Because its complexation forces are slightly weaker than phosphinic choices, stripping metal ions out of loaded P507 requires lower, less aggressive hydrochloric or sulfuric acid consumption.
캐리어 혼화성: Forms an exceptionally uniform, low-viscosity organic phase when blended with standard aliphatic kerosene diluents.
