N-Butyl Acetate, scientifically known as butyl ethanoate, is an ester with the chemical formula C6H12O2. Its molecular structure, derived from n-butanol and acetic acid, gives it a unique set of physical and chemical properties that make it highly valuable across various industries. Understanding these properties is essential for anyone involved in its application or sourcing.

One of the defining characteristics of N-Butyl Acetate is its appearance: a clear, colorless liquid with a distinctly sweet, fruity odor, often compared to bananas or apples. This pleasant aroma contributes to its use in fragrances and flavorings. Chemically, it is miscible with most common organic solvents like alcohols and ethers, but only slightly soluble in water. This solubility profile dictates its effectiveness in different formulations.

The production of N-Butyl Acetate typically involves the Fischer esterification process, where n-butanol reacts with acetic acid in the presence of a sulfuric acid catalyst. This reaction yields butyl acetate and water. The efficiency and purity of the resulting product are highly dependent on the reaction conditions and subsequent purification steps. For those interested in buying n-butyl acetate, knowing the production methods can offer insights into potential impurities and quality variations.

Key physical properties such as a boiling point of approximately 126.1 °C, a melting point of -78 °C, and a flash point of around 22 °C classify it as a flammable liquid. These parameters are crucial for safe handling, storage, and transportation. The chemical properties of butyl acetate, such as its solvency power for a wide range of materials including nitrocellulose, resins, and oils, are what make it so versatile.

When considering n-butyl acetate suppliers, it’s important to look for those who provide detailed specifications and adhere to quality standards. The purity of n-butyl acetate, often specified as 99.5% or higher, along with low levels of n-butanol, water, and acidity, ensures optimal performance in demanding applications. For instance, its use as a solvent in coatings and printing inks requires a consistent and high-purity product to achieve predictable results.

In summary, the chemistry of N-Butyl Acetate, from its molecular structure to its production methods and physical properties, underpins its widespread industrial utility. Whether for its solvent capabilities or its aromatic qualities, a thorough understanding of its chemical nature is fundamental.
