Diethylhexanol, also known by its scientific name 2-Ethylhexanol or 2-EH for short, is a long-chain, branched organic alcohol that has many applications in the chemical and petrochemical industries. Manufacturers use this compound to produce various plasticizers, lubricants, fuel additives, paints, and coatings. It ranks among the most economically important alcohol derivatives.
Chemical Structure and Properties of Diethylhexanol
Chemical Formula: C₈H₁₈O
- Molecular Mass: 130.23 g/mol
- Boiling Point: About 184°C
- Appearance: Colorless, oily liquid with a mild, sweet odor
- Solubility: Insoluble in water but soluble in most organic solvents such as ethanol, acetone, and ether
Diethylhexanol has a long chain with a side branch, which makes it behave in a special way in chemical reactions. It is stable at room temperature and does not evaporate easily, which is important in many of its industrial applications.
4 Industrial Uses of Diethylhexanol (2-EH)
1. Production of PVC plasticizers (plasticizers)
The largest use of 2-EH is in the production of dioctyl phthalate (DOP), one of the most widely used PVC plasticizers. This compound makes plastic products more flexible, elastic and durable.
2. Fuel and lubricant additives
In the oil and petrochemical industries, manufacturers use 2-EH as a raw material to produce diesel fuel additives that improve the cetane number and reduce pollution.
3. Paint and resin production
In the formulation of moisture and heat resistant paints, coatings and adhesives, diethylhexanol plays an important role. Manufacturers also use it as a solvent or reactive agent in producing acrylates and maleates.
4. Use in detergents and cosmetics
Formulators use diethylhexanol in some detergents, cleaners, and even perfumes due to its high solubility and mild odor.
Dangers and safety tips of diethylhexanol
- Inhaling its vapor may irritate the respiratory system.
- Direct contact with skin or eyes can cause burns or inflammation.
- There should be adequate ventilation in enclosed spaces.
- Experts recommend wearing gloves, safety glasses, and a mask.
Storage conditions of diethylhexanol
- Store in closed, solvent-resistant containers.
- Keep away from heat sources and direct sunlight.
- Store in a cool, dry, and well-ventilated area.
Market and purchase of diethylhexanol in Iran
- Product purity (usually above 99%)
- Production origin (European, Asian or domestic production)
- Packaging type (metal barrel or IBC tanks)
- Daily price of diethylhexanol, which varies depending on exchange rates and market conditions.
Diethylhexanol (2-EH) is one of the most important industrial alcohols that, due to its special chemical properties and wide applications, plays a key role in the petrochemical, paint, plastic and fuel industries. If you are active in the field of production, export or import of chemicals, familiarity with the characteristics and applications of 2-EH will be essential for you.
