Ya-(2-ethylhexyl) asidi ya fosforasi

Ya-(2-ethylhexyl) asidi ya fosforasi (universally designated in the hydrometallurgical industry as D2EHPA, DEHPA, HDEHP, or P204) is the world’s most widely utilized acidic organophosphorus solvent extraction (SX) reagent. Featuring a symmetric, branched di-ester molecular structure, this compound serves as the primary chemical workhorse for separating multivalent metal ions in base metal refining, lithium-ion battery recycling, and lanthanide processing.

Core Industrial Applications:
By managing the operational pH of the incoming pregnant leach solution, plants can isolate specific targets cleanly:

A. EV Battery Recycling:
In closed-loop hydrometallurgical recycling of ternary lithium-ion batteries, separating manganese from cobalt and nickel.
D2EHPA reaches its peak loading capacity for manganese while completely rejecting cobalt and nickel into the raffinate, creating a clean downstream path for high-purity cathode precursor production.
B. Zinc Hydrometallurgy & Zinc Electrowinning:

D2EHPA is the baseline reagent for the purification of zinc from sulfuric acid leach liquors. It selectively extracts zinc away from vast backgrounds of calcium, magnesiamu, na alumini, concentrating the zinc into a high-tenor advance electrolyte suitable for direct electrowinning cell houses.

C. Rare Earth Element (Ree) Processing:
Used in the initial fractionation stages of lanthanide refining blocks to separate light rare earth elements (Lrees) from heavy rare earth elements (HREEs). Because HREEs bind more strongly to the phosphoric acid matrix, they are selectively loaded while LREEs pass through the mixer cascades.
