Chemical name of P507 extractant: 2-ethylhexyl phosphate mono-2-ethylhexyl ester, molecular formula: [CH3 (CH2) 3CH (C2H5) CH2O] [CH3 (CH2) 3CH (C2H5) CH2] HPO2 or one of C16H35O3P, colorless or light yellow transparent oily liquid.

P507 extractant is acidic phosphorus extractant, which is called 2-ethylhexyl phosphate mono-2-ethylhexyl ester in full, and is colorless or yellowish, oily, transparent and liquid.

The main functions of extractants are to separate the main metal ions and impurity metal ions, enrich the concentration of main metal ions, purify metal ions, change the type of anions, etc.

Is extractant p507 dangerous? The answer is no. In fact, the toxicity of P507 is not strong. If the sealing of the extraction equipment is not good or the ventilation of the site is not good, it is at most an unpleasant smell.

In addition, extractants can be mainly used in China's non-ferrous metals through hydrometallurgical technology industry, such as copper, zinc, cobalt nickel, cadmium, gold and silver, platinum group metals, rare earth and other industries.

Metal extractants are mainly composed of seven common hydrogen ions, such as phosphoric acid, ammonium salt, benzene, or hydroxyl groups substituted by long-chain alkyl groups. When metals combine with these extractants, they become organometallic compounds that are soluble in organic solvents.

Due to the different analysis on the combination and development ability of various metals of the enterprise to these extractants, the order of metal extraction by these extractants is different, so as to separate these research metal ions.

Sinochem can seriously tell you that P507 extractant is almost harmless because it is widely used in industry, such as P204 for extracting zinc, indium, iron, etc.

They are basically pure, but diluents, such as kerosene, are added in the process of use to reduce the viscosity of extracted organics for separation.

P507 extractant cannot react with the solvent of the original solution. Common extractants for separating funnel extraction: benzene, alcohol, kerosene, straight chain gasoline, ethane and cyclohexane. Don't forget that water is an easily available extractant.

The above extractants are mainly physical extractants. At present, the industry, especially China's metallurgical industry, uses a large amount of funds for chemical extractants, which are widely studied and applied to groceries, purification, separation, product technology preparation, etc.

Most industrial extractants are soluble in organic solvents, and the commonly used organic solvent is sulfonated kerosene. Because it is cheap and easy to get, it has synergistic effect on extractants. Because it contains a small amount of aromatic hydrocarbons. Dissolving in organic solvent can improve the extraction capacity of technical extractants, enhance the solubility of Chinese metal extracts, reduce user viscosity, reduce volatile energy, and reduce the solubility in water.

P507 extractant is mainly used in the hydrometallurgical industry of copper, zinc, cobalt nickel, cadmium, gold, silver, platinum group metals, rare earth and other non-ferrous metals.

Organic phosphorus extractants can be widely used in the extraction and separation of nuclear fuel, the enrichment of rare metals, precious metals and non-ferrous metals, the purification of industrial wastewater, and the extraction and separation of organic acids, bases and substances.
