What Is the Boiling Point and Chemical Formula of Ethyl Acetate (Ethyl Ethanoate)

Overview

Boiling point of ethyl acetate: 77.1°C (170.8°F) at standard atmospheric pressure (760 mmHg / 1 atm)
Chemical formula: C₄H₈O₂ (molecular) / CH₃COOCH₂CH₃ (structural)
Its moderate boiling point and balanced solvency make it a versatile choice across adhesives, printing inks, pharmaceuticals, food processing, and advanced manufacturing industries.

What Is Ethyl acetate CAS 141-78-6?

CAS 141-78-6 Ethyl acetate is one of the most widely used industrial solvents worldwide. Most industries use ethyl acetate as a solvent for adhesives, printing inks, herbicides, and paints. This compound is colorless and results from an interaction between ethanol and acetic acid. Its chemical formula is C4H8O2.

What Is the Boiling Point of Ethyl Acetate?

The boiling point of ethyl acetate chemical (CAS 141-78-6) is approximately 77.1°C (170.8°F) at standardatmospheric pressure (760 mmHg). It is a colorless liquid with a fruity odor, commonused as a solvent, and has a relatively low boiling point, making it easy to evaporate.

Why this boiling point matters for industry?

This relatively low, moderate boiling point gives ethyl acetate a fast evaporation rate (6.2 times faster than n-butyl acetate, per industry benchmarks). This property delivers key practical benefits:

• Enables quick-drying paints, varnishes, and coating formulations
• Supports efficient solvent removal in pharmaceutical extraction and purification
• Delivers fast set times for packaging adhesives and printing inks
• Minimizes residual solvent in finished consumer and industrial products
• Compared to common solvents, ethyl acetate solvent boils higher than diethyl ether (34.6°C) but lower than toluene (110.6°C), striking an ideal balance between volatility and ease of handling.

Chemical Formula of Ethyl Acetate/EtOAc

• Molecular formula: C₄H₈O₂
• Structural formula: CH₃COOCH₂CH₃
• It is an ester compound formed by the reaction of ethanol and acetic acid.

Applications of Organic Solvent ethyl acetate

Because of its moderate boiling point (77.1°C), ethyl acetate solvent is widely used in:

• Food Industry: As an additive, E1504 is used in fruit flavorings, soft drinks, liqueurs, and confectionery. It is also used in the extraction of caffeine from coffee.
• Pharmaceuticals and Laboratories: Ethyl Acetate(EtOAc) is used in the production of anti-inflammatory drugs, anti-allergy medications, and other pharmaceuticals. It is also a common solvent in laboratory chromatographic analysis.
• Paint Industry: Ethyl Acetate CAS 141-78-6 is a key solvent in the production of paints and varnishes.
• Printing: Used for printing inks and cleaning printing plates.
• Leather Products: Mixed with alcohol to produce artificial leather.
• Cosmetics: Primarily used in nail polish remover and skincare products; its volatility is lower than acetone.

Safety and Handling Guidelines

CAS 141-78-6 Ethyl acetate has low acute toxicity relative to many industrial solvents, but proper handling is required due to its high flammability:

1. Use only in well-ventilated areas or fume hoods to avoid concentrated vapor inhalation, which may irritate respiratory tracts
2. Store away from open flames, sparks, and heat sources; keep containers tightly sealed when not in use
3. Wear safety goggles and chemical-resistant gloves to prevent skin and eye irritation
4. In case of fire, use carbon dioxide, dry chemical, or foam extinguishers (do not use water)

Is ethyl acetate a green solvent?

Ethyl acetate is classified as a green solvent for modern industrial use:

1. Biodegradable: Breaks down naturally in the environment with minimal long-term ecological impact
2. Renewable feedstock: Can be manufactured from bio-based ethanol and acetic acid (derived from sugarcane, corn, or other plant sources), reducing fossil fuel reliance
3. Low residual risk: Leaves minimal harmful residue in finished products and industrial waste streams

FAQ

Q: What purity of ethyl acetate should I buy for industrial use?

A: For most industrial applications, buyers typically choose ≥99.5% purity ethyl acetate. Applications requiring higher consistency, such as pharmaceutical or laboratory use, may require additional specifications and quality documentation.

Q: How can I choose a reliable ethyl acetate (CAS 141-78-6) supplier?

A: A reliable supplier should have:

• Stable factory cooperation and supply capability
• Export experience for international shipments
• Consistent quality control
• Complete documentation support
• Flexible packaging options such as drums, IBC tanks, and ISO tanks

If you are looking for a dependable partner for stable sourcing and professional export support, GNEE BIO is a strong choice.

q: Is ethyl acetate harmful?

A: While ethyl acetate chemical is less harmful than many other chemicals, it can still cause irritation to your skin or breathing passages. It's important to use it in a well-ventilated area and wear protective gear to keep safe.

q: What is the melting point of ethyl acetate?

A: The melting point of ethyl acetate is approximately -83.6°C.

q: Is ethyl acetate polar or nonpolar?

A: It is a moderately polar compound, containing a nonpolar ethyl group, a polar carbonyl (C=O) group and a polar oxygen atom.

Q: Is ethyl acetate the same as acetone?

A: No. While both are common industrial solvents, ethyl acetate is an ester (C₄H₈O₂) with a higher boiling point (77.1°C vs. 56°C for acetone) and lower volatility. Acetone is a ketone (C₃H₆O) with stronger solvency for some materials but faster evaporation.

Q: Does ethyl acetate dissolve in water?

A: It is slightly soluble in water (8.3 g per 100 mL at 20°C) and fully miscible with most organic solvents.

Q: Is ethyl acetate safe for food contact?

A: Yes, when used in approved concentrations. It is classified as food additive E1504 by global regulatory bodies and is widely used in food flavorings and extraction processes.
