2-EH is commonly known as 2-Ethylhexanol, which is a type of branched-chain alcohol with eight carbon atoms. It is a clear,colorless liquid with a characteristic odor, insoluble in water but soluble in most organic solvents.
Production
2-Ethylhexanol is primarily produced through the Oxo synthesis process, where propylene and synthesis gas are used as raw materials. The process involves the hydroformylation of propylene to form butyraldehyde, which is then condensed and hydrogenated to produce 2-Ethylhexanol.
Applications
1. Plasticizers: The major application of 2-Ethylhexanol is in the production of plasticizers such as Di-2-ethylhexyl phthalate(DOP), Trimellitic acid tri-2-ethylhexyl ester (TOTM), and Di-2-ethylhexyl adipate (DOA). These plasticizers are widely used in PVC products, automotive applications, building and construction, hoses, and flooring.

2. Coatings and Adhesives: It is used to produce 2-Ethylhexyl acrylate, which is a key component in coatings and adhesives.

3. Other Chemicals: 2-Ethylhexanol serves as an intermediate for producing various chemicals, including diesel fuel additives,lubricant oil additives, pharmaceuticals, personal care products, crop protection agents, and mining chemicals.

4. Solvents and Additives: It is used as a low-volatility solvent and as a cetane improver when reacted with nitric acid. It is also used in the production of epoxy reactive diluents for coatings, adhesives, and sealants.

Properties
* Molecular Formula: C₈H₁₈O
* Molecular Weight: 130.23 g/mol
* Boiling Point: 184.7°C
* Melting Point: < -76°C
* Density: 0.83 g/cm³ at 20°C
* Solubility: Slightly soluble in water (0.6 g/L at 20°C), but miscible with ethanol, ether, acetone, benzene, and chloroform.

Safety and Handling
2-Ethylhexanol is combustible and should be stored below +30°C. It is incompatible with strong oxidizing agents and strong acids.
It has a low toxicity level, with an oral LD50 for rats ranging from 3200 to 7600 mg/kg. However, proper precautions such as keeping the storage area well-ventilated and using personal protective equipment are recommended.
In summary, 2-Ethylhexanol (2-EH) is a versatile chemical with a wide range of applications in various industries, primarily as a precursor to plasticizers and other specialty chemicals.
