butyyliakrylaatti

Butyyliakrylaatti, or butyl acrylate, is an acrylate ester used mainly as a monomer in the synthesis of polymers and copolymers. Its chemical formula is C7H12O2. It is typically a colorless to pale liquid at room temperature with a characteristic acrylate odor. It is immiscible with water and soluble in many organic solvents. The presence of the acrylate C=C double bond makes it highly reactive in radical polymerization.

Production and handling characteristics: Butyl acrylate is produced by esterification of acrylic acid with one‑butanol in the presence of an acid catalyst. In industry, polymerization inhibitors such as hydroquinone or tert‑butylcatechol are added to prevent premature curing during storage and transport. The material is usually sold stabilized, sometimes as a solution in hydrocarbon solvents or stabilized neat.

Applications and properties: This monomer is widely used in the production of acrylic resins, coatings, paints, adhesives, sealants, and specialty polymers. It is often copolymerized with styrene, methacrylates, acrylates, and vinyl esters to tailor properties such as flexibility, toughness, and adhesion. The resulting polymers can form clear coatings and durable plastics, with varying hardness and chemical resistance depending on formulation and processing conditions.

Safety and handling: Butyl acrylate is flammable and can cause irritation to skin, eyes, and the respiratory tract. It should be handled in well‑ventilated areas with appropriate personal protective equipment, including gloves and eye protection. Storage should be in a cool, dry place away from heat and oxidizers, with inhibitors maintained to prevent undesired polymerization. Proper containment is advised for spills or leaks.
