What is ethyl acetate C4H8O2 (CAS 141-78-6)?

In the world of industrial chemicals, few solvents strike the perfect balance between performance, safety, and versatility quite like ethyl acetate solvent. From high-precision cleaning to efficient extraction and formulation use, ethyl acetate is a widely adopted solution across multiple sectors. TIANJIN GNEE BIOTECH CO., LTD., as a professional manufacturer and supplier of Ethyl Acetate (EtOAc, CAS 141-78-6), provides high-quality solvent solutions for global industries.

What Is Ethyl Acetate (CAS 141-78-6)?

Ethyl acetate (chemical formula: C4H8O2) is a colorless, low-boiling, volatile organic compound with a characteristic fruity odor. As a medium-polarity solvent, it can dissolve a wide range of substances, making it highly valuable in formulations and processes that require fast evaporation and minimal residue.

It is widely used as a solvent in chemical reactions or preparations. That's why it is manufactured on a large scale. Ethyl acetate is also known as ethyl ethanoate. It is also abbreviated as EtOAc. It is mainly used as a solvent in different reactions.

Properties of Ethyl Acetate

Physical Properties
This clear, volatile liquid carries a distinct fruity scent, boiling at 77°C and melting at -83.6°C. Moreover, its flammability kicks in at a flash point of -4°C, and though miscible with alcohols, ethers, and hydrocarbons, it only dissolves modestly in water (8.7% at 20°C).

Chemical Properties
Formed through the condensation of acetic acid and ethanol, this ester remains stable but can hydrolyze under acidic or basic conditions, reverting to its original components. Moreover, it participates in a range of reactions, including:

• Oxidation: It can undergo combustion in the presence of oxygen, producing carbon dioxide and water.
• Nucleophilic addition: The carbonyl group can undergo nucleophilic addition reactions with nucleophiles like alcohols or amines.

Structure and Formula for Ethyl Acetate

The formula of Ethyl Acetate can be easily memorized because as the name suggests it contains ethyl group (CH₂-CH₃ or C₂H₅) and acetate group (CH₃COO).

• The extended formula for ethyl acetate is CH₃COOCH₂CH₃

• Chemical Formula of Ethyl Acetate C₄H₈O₂

Safety and Handling of Ethyl Acetate (C4H8O2)

Storage and Handling Guidelines

• Store in tightly sealed containers in a cool, dry, and well-ventilated area.
• Keep containers upright to prevent leakage.
• Use ethyl acetate in well-ventilated areas, and avoid contact with skin, eyes, and inhalation of vapors.
• Follow good industrial hygiene practices, including washing hands after handling the chemical.

Regulatory and Safety Standards

Ethyl acetate is subject to specific regulations regarding its handling and storage, particularly due to its flammability. In Korea, for instance, the designated quantity for ethyl acetate is 20,000 kg, and it is managed similarly to other flammable substances like benzene and toluene. These regulations help in preventing accidents and ensuring post-management measures are in place.

Ethyl Acetate industrial uses

Ethyl Acetate is valued for its balance of performance, purity, and safety, making it a preferred solvent in many industries:

• Coatings and Paints: Used in automotive, industrial, and wood coatings for superior film formation and fast drying.
• Adhesives and Sealants: Enhances open time, tack, and adhesion properties in solvent-based adhesive systems.
• Printing Inks: Common solvent in flexographic, gravure, and rotogravure printing due to its clean evaporation profile.
• Pharmaceuticals: Used as a solvent and extraction medium for active ingredients.
• Cleaning and Degreasing: Removes oils, greases, and contaminants from surfaces efficiently.
• Laboratory and Analytical Use: Functions as a reagent or solvent in analytical testing and synthesis.
