N-Butyl Acetate

Product Overview

N-Butyl Acetate (Reagent Grade) is a high-purity organic ester with the formula C₄H₈O₂ (CH3COO(CH2)3CH3). Known for its characteristic fruit-like odor, this solvent offers excellent solvency for a wide range of resins, polymers, and cellulose derivatives. As a Reagent Grade chemical, it meets strict purity standards, making it suitable for sensitive industrial applications where low impurity profiles are critical. It features a medium evaporation rate, which promotes flow and leveling in coatings, and possesses a flash point of 22°C (72°F).

Ideally suited for industrial environments, N-Butyl Acetate serves as a primary solvent in the manufacture of lacquers, artificial leathers, photographic films, and safety glass. It is also utilized as an extraction solvent in chemical processing and as a cleaning agent for degreasing machinery. This product is available in pack sizes ranging from 1 quart to 330-gallon totes to accommodate both laboratory research and large-scale manufacturing requirements. Proper handling protocols for Class 3 Flammable Liquids must be observed.

Safety Precautions

N-Butyl Acetate is classified as a flammable liquid and vapor. It must be stored in a cool, well-ventilated area, away from ignition sources, heat, and direct sunlight. Keep containers tightly closed when not in use. This chemical is incompatible with strong oxidizing agents, strong acids, and strong bases.

Personal Protective Equipment (PPE): Users should wear chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Ensure adequate ventilation or use appropriate respiratory protection if vapor concentrations exceed exposure limits. In the event of a spill, eliminate all ignition sources and contain with non-combustible absorbent material. Refer to the Safety Data Sheet (SDS) for comprehensive hazard information and emergency response procedures.

Benefits

High Purity Profile: Reagent Grade specifications ensure consistent performance in sensitive chemical reactions and formulations.
