BUTYL ACETATE (C₆H₁₂O₂)

---

ABOUT:

Butyl acetate is usually produced through the esterification reaction between butanol and acetic acid in the presence of an acid catalyst. The reaction typically occurs at a temperature of around 60-70°C and the catalyst used is sulfuric acid. The mixture is then distilled to separate the butyl acetate from the remaining reactants and by-products.Butyl acetate is used as a solvent for various automotive coatings, adhesives, and resins.

CHEMICAL PROPERTIES:

• It is flammable and can ignite easily.
• It can react with strong acids and strong oxidizing agents.
• It is volatile and can easily evaporate into the air.
• Is soluble in water and other organic solvents.
• Is a relatively stable compound, but it can decompose under conditions of high temperature or exposure to light.

APPLICATIONS:

• It is used in the production of adhesives, inks, and surface coatings for automotive parts and components. 
• It is also used in the cleaning of engine parts and as a starting fluid for diesel engines.
• It is a common ingredient in perfumes, colognes, and aftershaves, adding a fruity, sweet aroma to the product.
• It is used as a solvent in the production of certain food packaging materials.
• It is used as a flavor and fragrance ingredient in food and beverage products. 
• It is used to dissolve and disperse dyes, pigments, and other chemical treatments applied to the leather to enhance its appearance and durability. 
• Butyl acetate is used in the leather finishing process to improve the softness, flexibility, and shine of the leather surface.
• Butyl acetate can also act as a thinner for some enamels, varnishes, and stains, allowing for better application and a smoother finish. 
• It is known for its low volatility, low toxicity and fast evaporation rate which makes it a preferred choice for certain types of paint and coating products.
• It is used as a plasticizer in the manufacture of nitrocellulose-based coatings, and as a volatile component in the formulation of lacquers, enamels, and varnishes to improve flow and leveling characteristics.
• It is used as a solvent to manufacture many Active Pharma Ingredients, including PEN-G.

SAFETY MEASURES:

• Use proper personal protective equipment (PPE), such as gloves, safety glasses, and a respiratory mask.
• Store butyl acetate in a well-ventilated area, away from heat sources and ignition sources.
• Keep butyl acetate containers closed when not in use to prevent evaporation and reduce the risk of fire.
• Avoid using electrical equipment in areas where there is a potential for butyl acetate vapors to ignite.
• Do not eat, drink, or smoke in areas where butyl acetate is being used.
• If you experience any symptoms of exposure, such as eye irritation, headache, dizziness, or respiratory problems, immediately remove yourself from the area and seek medical attention if necessary.
• In the event of a fire involving butyl acetate, use a dry chemical fire extinguisher or foam to extinguish the flames.
