ethylacrylaat

Ethyl acrylate is the ethyl ester of acrylic acid. Its IUPAC name is ethyl prop-2-enoate, and it has the chemical formula C5H8O2 with a molecular weight of about 100.1 g/mol. It is a colorless, volatile liquid that has a characteristic acrylate odor. Ethyl acrylate is soluble in many organic solvents and has limited water solubility.

Ethyl acrylate is primarily used as a monomer in radical polymerization to form poly(ethyl acrylate) and to prepare copolymers for coatings, adhesives, sealants, textiles, and packaging materials. It is often combined with other acrylate or vinyl monomers to tailor properties such as flexibility, adhesion, and hardness. In industry, it is frequently handled as a reactive monomer in controlled environments to manage polymerization risk.

Production typically involves esterification of acrylic acid with ethanol in the presence of an acid catalyst, followed by purification to remove water and inhibitors. To prevent premature polymerization during storage and handling, inhibitors such as hydroquinone are commonly added and the material is kept under appropriate temperature and atmosphere conditions.

Reactivity and safety considerations: Ethyl acrylate contains a vinyl double bond that readily undergoes radical polymerization, which can be exothermic. It is flammable and can irritate the eyes, skin, and respiratory tract. Storage and handling require appropriate engineering controls, including ventilation, inert or low-oxygen atmospheres when necessary, and the use of stabilizers and polymerization inhibitors to maintain material integrity.

Environmental and regulatory notes: As with many acrylates, spills should be contained to prevent release to soil or water, and waste should be managed according to local regulations.
