What is the P507 extractant? A comprehensive analysis of its chemical name, applications, and safety.

P507 extractant Chemical name: 2-Ethylhexyl phosphate mono-2-ethylhexyl ester; molecular formula: [CH3(CH2)3CH(C2H5)CH2O][CH3(CH2)3CH(C2H5)CH2]HPO2, or C16H35O3P. It is a colorless or pale yellow, transparent oily liquid.

P507 extractant It is an acidic phosphorus extractant, chemically known as 2-ethylhexyl phosphate mono-2-ethylhexyl ester, and appears as a colorless or slightly yellowish oily, transparent liquid.

The primary functions of an extractant are to separate major metal ions from impurity metal ions, concentrate the concentration of the target metal ions, purify the metal ions, and modify the anion species, among others.

Is the extractant P507 hazardous? The answer is no. In fact, P507 is not highly toxic. If the extraction equipment is poorly sealed or the ventilation is inadequate, the worst that might occur is an unpleasant odor.

In addition, extractants are primarily used in China Nonferrous’s hydrometallurgical operations for metals such as copper, zinc, cobalt and nickel, cadmium, gold and silver, platinum-group metals, and rare earth elements.

Metal extractants are primarily composed of seven common functional groups, including phosphoric acid, ammonium salts, and benzene, as well as hydroxyl groups substituted by long-chain alkyl groups. When metals bind with these extractants, they form metal–organic complexes that are soluble in organic solvents.

Due to the varying binding affinities of different metals to these extractants, the order in which these extractants selectively extract the metals differs, thereby enabling the separation of these metal ions.

Sinochem can sincerely tell everyone, p507 extractant There is virtually no risk, as this extractant is widely used in industry—for example, for the extraction of zinc, indium, iron, and other metals using P204.

They are essentially pure, but diluents such as kerosene are added during use to reduce the viscosity of the extracted organic compounds for easier separation.

P507 extractant It must not react with the solvent of the original solution. Common extraction solvents used in a separatory funnel include benzene, ethanol, kerosene, straight-chain gasoline, ethane, and cyclohexane. Do not forget that water is an easily accessible extractant.

The aforementioned extractants are primarily physical extractants. At present, in industry—particularly in China’s metallurgical sector—a substantial amount of funding is being allocated to chemical extractants, which are extensively studied and applied in areas such as impurity removal, purification, separation, and the preparation of advanced materials.

In industrial applications, extractants are typically soluble in organic solvents; a commonly used organic solvent is sulfonated kerosene. This solvent is inexpensive and readily available, and it exhibits a synergistic effect with the extractant due to its minor aromatic hydrocarbon content. Solubility in organic solvents enhances the extractant’s extraction efficiency, improves the solubility of metal‑extract complexes, reduces viscosity, lowers volatility, and decreases water solubility.

P507 extractant It is primarily used in the hydrometallurgical processing of nonferrous metals, including copper, zinc, cobalt and nickel, cadmium, gold, silver, platinum-group metals, and rare earth elements.

Organophosphorus extractants are widely employed in the extraction and separation of nuclear fuels, the concentration of rare, precious, and non‑ferrous metals, the treatment of industrial wastewater, and the extraction and separation of organic acids, bases, and other substances.
