2-Ethylhexanoic Acid (CAS 149-57-5) is a versatile organic compound widely used across various industries. This transparent, colorless liquid exhibits a slight odor and excellent solubility properties. It is soluble in hot water, ether, and ethanol, making it an ideal ingredient for numerous applications. With a molecular formula of C8H15O2 and a molecular weight of 143.20, this compound is recognized for its stability and effectiveness in diverse formulations.
Physically, 2-Ethylhexanoic Acid has a melting point of -8.3°C and a boiling point of 228°C, alongside a relative density of 0.9031. It is commonly employed in producing metal salts, essential as drying agents in coatings and paints, and its esters are pivotal in manufacturing plasticizers and carboxybenzyl penicillin.
Its density is 0.9077 g/cm³ at 20℃ (0.9031 g/cm³ at 25℃), with a stable boiling point of 228.0℃ (at 760 mmHg) and a low melting point of -59℃, so it is not easy to solidify in low-temperature environments. The flash point is 116.6℃ and the ignition point is 371℃, leading to controllable fire and explosion risks under conventional storage conditions. Its water solubility is 2 g/L at 20℃; it is slightly soluble in cold water but easily soluble in organic solvents such as ethanol, ether, and acetone, and can also be miscible with hot water, showing strong solubility adaptability.
It has a molar refraction of 40.63, a polarizability of 16.10×10⁻²⁴ cm³, a topological polar surface area of 37.3, and a LogP value of 2.72. These molecular parameters enable it to form stable salts with metal ions (such as zirconium, cobalt, and zinc salts), serve as a high-quality raw material for ester synthesis, and exhibit good reaction selectivity in organic synthesis reactions, reducing the generation of by-products.
It is a low-toxicity chemical, with an LD₅₀ of 3000 mg/kg for oral administration in rats, resulting in low harm to the human body under standardized operation. However, it should be noted that it is irritating to the skin and mucous membranes and will release irritating acid mist when heated. Standard protective measures are required to avoid risks, and its overall safety is above the medium level among similar carboxylic acid intermediates.
As a key intermediate, 2-ethylhexanoic acid is widely used in multiple fields such as industry, pharmaceuticals, and daily chemicals. The specific application scenarios are as follows:
The metal salts formed by its reaction with metal ions such as zirconium, cobalt, and molybdenum are high-efficiency driers in the coating and paint industry, which can accelerate the curing speed of paint films and improve adhesion strength. Its tin salts can be used as anti-aging additives for plastic pipes, and barium salts and cadmium salts are core components of PVC heat stabilizers, which can effectively prevent PVC degradation due to high temperature during processing.
The ester compounds generated by its self-esterification are basic plasticizers, among which glycerides are even called "excellent plasticizers". They have good compatibility with polymer materials such as plastics and rubber, can significantly improve the flexibility and low-temperature resistance of products, and are often used in the production of flexible PVC products and rubber seals.
It is a key raw material for the synthesis of carbenicillin (a broad-spectrum antibiotic used in the treatment of respiratory and urinary system infections caused by sensitive bacteria). At the same time, it can be used as an active ingredient of fungicides and a basic component of metal lubricants, integrated into cosmetic formulations to improve the stability of skin feel. It can also participate in the synthesis of various dyes (such as acid dyes) and fragrances (such as ester fragrances) to expand the functions of daily chemical products.
It serves as a core intermediate in organic synthesis reactions and can be involved in the preparation of various fine chemicals. Meanwhile, due to its good solubility, it can be used as a component of cleaning agents to remove oil stains on metal surfaces or as a solvent for the dissolution and dispersion of some high-polarity substances.
This product belongs to Toxic Substance of Class 6.1, with a hazardous goods transport code of UN 3265 and a packing group of II. The transportation process must strictly comply with the *Regulations on the Safety Administration of Hazardous Chemicals* and relevant transportation standards.
It is packaged in corrosion-resistant polyethylene drums or iron drums lined with anti-corrosion coatings. The drum mouths must be tightly sealed to prevent leakage. Clear hazardous goods labels (including GHS08 hazard symbol, "Corrosive" and "Flammable" warning words, and emergency contact information) must be affixed to the outside of the packaging.
Transport vehicles must have the qualification for hazardous goods transportation, and the compartments must be clean and dry. Mixed loading and transportation with oxidants, strong acids, strong alkalis, and other goods should be avoided. During transportation, protection from sunlight and rain is required; sunshade measures should be taken in summer, and no special heat preservation is needed in winter (since it only solidifies below -59℃ due to its low melting point). The vehicle should travel at a constant speed during the journey to avoid sudden braking and severe jolting that may cause packaging damage.
In case of leakage during transportation, the vehicle must be immediately moved to a safe area (away from fire sources, water sources, and crowds). Operators should wear gas masks, goggles, and corrosion-resistant gloves. Small leaks should be collected with activated carbon or inert adsorbent materials, and large leaks should be contained with dikes. It is strictly forbidden for the leaked material to flow into water bodies or soil. The remaining waste after treatment must be handed over to a professional hazardous waste treatment organization for disposal.
