1. Basic Information of Bis(2-ethylhexyl) Phosphate Cas 298-07-7

Bis(2-ethylhexyl) Phosphate, with the CAS number 298 - 07 - 7, is a chemical product that is factory - supplied at a low price. It is also known as DEHPA. The molecular formula of this compound is C₁₆H₃₅O₄P, and its molecular weight is approximately 322.42 g/mol. It is a colorless to pale - yellow liquid at room temperature. The density of Bis(2 - ethylhexyl) phosphate is about 0.973 g/cm³, and its boiling point is around 209 - 210 °C at 4 mmHg. It has a relatively low solubility in water but is soluble in many organic solvents such as ethanol, chloroform, and benzene.

2. Uses of Bis(2-ethylhexyl) Phosphate Cas 298-07-7

One of the primary uses of Bis(2 - ethylhexyl) phosphate is in the field of metal extraction. It can act as an extractant in the separation and purification of rare earth metals. In the hydrometallurgical processes, it forms complexes with metal ions, allowing for the selective extraction of certain metals from complex mixtures. This is crucial in the production of high - purity rare earth metals used in various high - tech applications, such as in magnets for electric vehicles and wind turbines.

It is also used as a plasticizer in the plastics industry. By adding Bis(2 - ethylhexyl) phosphate to plastics, it can improve the flexibility, durability, and workability of the plastic materials. This is especially useful in the production of PVC products, where it helps to reduce the brittleness of the plastic and make it more suitable for a wide range of applications, from pipes to cable insulation.

In addition, it serves as an anti - static agent in some industrial processes. It can reduce the build - up of static electricity on the surface of materials, which is important in industries where static electricity can cause problems such as dust attraction, sparking, or interference with electronic equipment.

3. Usage of Bis(2-ethylhexyl) Phosphate Cas 298-07-7

When using Bis(2 - ethylhexyl) phosphate in metal extraction, it is first dissolved in an organic solvent to form an organic phase. The aqueous solution containing the metal ions is then mixed with the organic phase. Through a series of extraction and separation steps, the metal ions are transferred from the aqueous phase to the organic phase. After extraction, the metal - loaded organic phase can be further treated to recover the metals. The dosage of Bis(2 - ethylhexyl) phosphate depends on the concentration of metal ions in the aqueous solution and the desired extraction efficiency.

In the plastics industry, it is added during the plastic manufacturing process. The appropriate amount of Bis(2 - ethylhexyl) phosphate is mixed with the plastic resin, and then the mixture is processed through methods such as extrusion, injection molding, or calendering. The exact amount added needs to be carefully determined according to the type of plastic, the desired properties, and processing requirements.

As an anti - static agent, it can be applied to the surface of materials by spraying, dipping, or coating. The concentration of the Bis(2 - ethylhexyl) phosphate solution used for these applications should be adjusted based on the surface properties of the material and the level of anti - static protection required.

4. Case Studies

In a large - scale rare earth metal extraction plant, Bis(2 - ethylhexyl) phosphate was used as the extractant. The plant was dealing with a complex ore containing multiple rare earth elements. By carefully optimizing the extraction process using Bis(2 - ethylhexyl) phosphate, they were able to achieve a high - purity separation of neodymium and praseodymium. The extraction efficiency of neodymium reached over 95%, and the purity of the separated neodymium product was above 99%. This not only improved the economic benefits of the plant but also met the high - quality requirements of the downstream manufacturers of neodymium - based magnets.

For a plastic manufacturing company, they added Bis(2 - ethylhexyl) phosphate to their PVC pipes production. Before using this plasticizer, their pipes were prone to cracking during installation and use. After adding an
