 Di-(2-ethylhexyl) phosphoric acid (D2EHPA 95% )

Reliable Supplier of Bulk Di-(2-ethylhexyl) phosphoric acid (D2EHPA)- Baysolvex D2EHPA. Free SGS inspection on 1st order. 

D2EHPA is used in the extraction of uranium salts from solutions containing sulphates, perchlorates or chlorides. This process is called the ‘Dapex procedure’.

This is an organo-phosphorous compound with the formula (C8H17O)2PO2H which is a diester of phosphoric acid and 2-ethyl exanol. It is used in the solvent extraction of uranium and rare earth metals.

Kerosene is used as a solvent in the process. A complex is formed between conjugate base of D2EHPA and uranyl ions. The uranium is then stripped from the DEHPA-Kerosene solution using HCl, HF or carbonate solution.
