Butyl Acetate CAS 123-86-4
As a premier global chemical supplier, Sinochem delivers premium industrial-grade Butyl Acetate CAS 123-86-4 (specifically N-Butyl Acetate) tailored for demanding formulation and manufacturing applications. Characterized by a four-carbon butyl chain attached to an acetate functional group, this versatile carboxylate ester presents as a clear, colorless, and volatile transparent liquid with a distinctive sweet, fruity fragrance.
Our Butyl Acetate is highly valued across global markets for its exceptional solvency, optimal evaporation rate, and excellent miscibility with ethanol, diethyl ether, and most organic solvents, while remaining only slightly soluble in water.
- Superior Solvency Power: Highly effective at dissolving a vast spectrum of synthetic resins, polymers, and organic compounds, making it an indispensable process chemical.
- Balanced Evaporation Rate: Provides controlled drying times in surface finishes, preventing blushing or structural defects in industrial coatings and commercial printing inks.
- Versatile Compatibility: Blends seamlessly with other chemical intermediates and organic solvents without phase separation, allowing for flexible custom formulations.

Butyl ethanoate Applications
- High-Performance Coatings and Paints: Butyl Acetate acts as a foundational, premium solvent in automotive OEM coatings, industrial wood finishes, varnishes, nitrocellulose lacquers, and aircraft finishes. It ensures flawless film leveling, uniform thickness, and an ideal gloss finish.
- Advanced Printing Inks & Adhesives: It is widely formulated into flexographic, rotogravure, and screen printing inks, as well as stamp pad oils, ensuring precise dye/pigment dispersion. It also serves as an effective carrier solvent for resin-based adhesives and sealants.
- Industrial Cleaning & Degreasing Agents: Thanks to its robust lipid-dissolving capability, it is extensively utilized in metal surface detergents, automotive engine degreasers, lubricating oil removal agents, paint strippers, and specialized dry-cleaning formulations.
- Chemical Extraction & Intermediates: It is widely used as an efficient extraction agent in the pharmaceutical industry for isolating antibiotics and organic compounds, and serves as an essential flavoring ingredient in the fragrance industry.
Frequently Asked Questions
Q1: Why is Butyl Acetate preferred over other solvents in the paint industry?
A: Butyl Acetate offers a highly balanced evaporation rate compared to faster-evaporating solvents like acetone or slower ones like glycol ethers. This specific volatility ensures excellent flow, superior leveling, and prevents moisture entrapment or surface blushing in topcoats.
Q2: What precautions should be taken regarding its low flashing point (22°C)?
A: Since Butyl Acetate is classified as a Class 3 flammable liquid, its storage and operational areas must be equipped with localized exhaust ventilation, explosion-proof electrical systems, and reliable grounding lines to prevent static buildup. Non-sparking tools must be utilized during handling.
Q3: What is the difference between acetone and butyl acetate?
A: The primary differences between acetone and butyl acetate lie in their chemical structure, evaporation rates, and industrial applications:
Chemical Classification: Acetone is a ketone (CH3COCH3), while butyl acetate is a carboxylate ester (C6H12O2).
Evaporation Rate & Odor: Acetone is highly volatile and evaporates extremely fast with a sharp, pungent smell. Butyl acetate has a medium, controlled evaporation rate and features a distinctively sweet, fruity fragrance.
Water Solubility: Acetone is completely miscible in water, whereas butyl acetate is only slightly soluble.
Industrial Application: Acetone is typically used as a fast-acting stripping solvent or heavy-duty cleaner. In contrast, butyl acetate is preferred in high-performance paints, inks, and coatings because its balanced drying time ensures optimal leveling and prevents surface blushing.
