Tianjin Gnee Biotech Co., Ltd. provides high-quality industrial solvents, including ethyl acetate (CAS 141-78-6), which is widely used in coatings, adhesives, pharmaceuticals, food processing, and chemical manufacturing.
For buyers and distributors, understanding its core physical properties is important for product selection, formulation stability, storage, and transportation.
Chemical Structure and Formula
Ethyl acetate is an organic ester with the molecular formula C₄H₈O₂, consisting of four carbon atoms, eight hydrogen atoms, and two oxygen atoms.
It is formed through an esterification reaction between ethanol and acetic acid. Structurally, it contains an ethyl group (C₂H₅) connected to an acetate group (COO), which gives it typical ester characteristics such as volatility and good solvency performance.
Boiling Point of Ethyl Acetate
The boiling point of ethyl acetate is approximately:
- 77.1°C (170.78°F)
Because of this relatively low boiling point, Ethyl Acetate (etoac) evaporates quickly at room temperature. This makes it suitable for applications where fast drying is required, such as:
- Coatings
- Paint formulations
- Adhesives
- Printing inks
Density of Ethyl Acetate
The standard density of ethyl acetate is:
- 0.902 g/cm³ at 20°C
This value is widely referenced in industrial specifications and chemical databases.
In practice, small variations may occur depending on temperature and purity level, but 0.902 g/cm³ is generally accepted as the standard benchmark for industrial use.
Flash Point of Ethyl Acetate
Ethyl Acetate (etoac) has a flash point of:
- -4°C (24.8°F)
This indicates that it is a highly flammable liquid. Proper storage and handling conditions are required, especially in environments where ignition sources may exist.
Solubility of Ethyl Acetate
Ethyl acetate has good solubility behavior:
- Slightly soluble in water
- Fully miscible with many organic solvents such as ethanol and ether
This balanced solubility makes it useful in both polar and non-polar formulations, especially in extraction and purification processes.
Industrial Applications of Ethyl Acetate (Ethyl Ethanoate)
Paints and Coatings
Ethyl Acetate (Ethyl Ethanoate) is commonly used as a solvent in paints, varnishes, and surface coatings. It helps improve flow, leveling, and drying speed, making it ideal for industrial finishing applications.
Extraction and Purification
In chemical and pharmaceutical industries, Ethyl Acetate (etoac) is used to extract natural compounds such as essential oils and plant-based active ingredients. It is also used in purification processes due to its effective dissolving capability.
Food and Flavor Applications
In controlled industrial use, ethyl acetate is applied in flavor formulations, contributing fruity aroma notes in food essences and beverage flavoring systems.
Cosmetics and Personal Care
It is commonly found in products such as nail polish removers, perfumes, and hair sprays, where it acts as an efficient solvent for active ingredients.
Adhesives and Industrial Glues
Ethyl acetate is an important component in adhesive formulations, especially for packaging, labeling, and fast-drying glue systems.
Handling and Safety Guidelines
Although ethyl acetate is widely used, proper handling is necessary to ensure workplace safety.
Ventilation
Use in well-ventilated areas. Industrial applications should preferably be conducted with local exhaust ventilation or fume extraction systems to minimize vapor exposure.
Fire Safety
Keep away from heat sources, sparks, and open flames. Due to its low flash point, ethyl acetate vapors can form flammable mixtures with air.
Personal Protective Equipment (PPE)
Recommended protective measures include:
- Safety goggles or face shield to prevent eye exposure
- Protective gloves for skin contact prevention
- Respiratory protection when ventilation is insufficient
Conclusion
Ethyl acetate (CAS 141-78-6) is a versatile industrial solvent with well-defined physical properties, including a boiling point of 77.1°C and a density of 0.902 g/cm³ at 20°C. Its fast evaporation, strong solvency, and broad application range make it a key material in coatings, adhesives, pharmaceuticals, and chemical manufacturing.
For industrial buyers, understanding these properties is essential for selecting the right grade, ensuring production stability, and optimizing application performance.
