N-Butyl Acetate, a compound familiar to many in the chemical industry, is a highly versatile organic ester with a distinct profile of chemical properties that make it invaluable across numerous industrial sectors. With the CAS number 123-86-4 and the chemical formula C6H12O2, this clear, colorless liquid is more than just a solvent; it’s a critical component in the production of everyday items and advanced materials. This article aims to detail its key chemical characteristics and explore its extensive industrial applications, guiding potential buyers on how to source it effectively.

At its core, N-Butyl Acetate is the ester formed from the reaction of n-butanol and acetic acid. Its molecular weight is approximately 116.16 g/mol. Key physical and chemical properties include a boiling point of around 126.1°C and a melting point of -78°C, indicating it remains liquid across a wide operational temperature range. Its density is about 0.882 g/cm³ at 20°C. N-Butyl Acetate exhibits a characteristic fruity odor, often described as sweet or banana-like, which lends itself to applications in flavors and fragrances.

From a solvency perspective, N-Butyl Acetate is a highly effective solvent for a broad array of substances. It demonstrates excellent solubility for nitrocellulose, cellulose acetate butyrate, acrylic resins, vinyl copolymers, epoxies, and alkyds. This broad compatibility makes it an indispensable ingredient in the formulation of paints, lacquers, varnishes, and coatings. Its medium evaporation rate is another critical property, allowing for good flow and leveling during application while facilitating a relatively quick drying time. This balance is crucial for achieving smooth, high-quality finishes in demanding coating applications.

The industrial applications of N-Butyl Acetate are extensive. Primarily, it serves as a potent solvent in the coatings industry, contributing to the performance of automotive paints, industrial finishes, architectural coatings, and wood lacquers. Its ability to dissolve resins efficiently ensures proper film formation and adhesion. Beyond coatings, N-Butyl Acetate finds use in the manufacturing of printing inks, where it helps in pigment dispersion and ink drying. It is also a component in adhesives, leather finishes, and cleaning agents, owing to its effective degreasing properties.

The flavor and fragrance industry also utilizes N-Butyl Acetate for its pleasant fruity aroma, incorporating it into perfumes and food flavorings. In the plastic industry, it can act as a process solvent or intermediate. For those looking to buy N-Butyl Acetate, understanding these diverse applications is key to identifying its suitability for specific manufacturing needs.

As a chemical supplier, N-Butyl Acetate is offered with high purity (typically ≥99.5%) to meet stringent industrial requirements. Sourcing from a reputable manufacturer in China ensures access to a reliable supply chain, competitive pricing, and consistent product quality. When purchasing, it’s advisable to consider the packaging (often ISO drums) and inquire about bulk order discounts. Always consult the MSDS for detailed safety information, as it is a flammable liquid requiring careful handling.

In conclusion, the robust chemical properties of N-Butyl Acetate, including its excellent solvency and balanced evaporation rate, position it as a critical solvent for numerous industrial applications. By understanding its characteristics and partnering with reliable suppliers, businesses can leverage N-Butyl Acetate to enhance product quality and manufacturing efficiency.
