Butyl acrylate is an organic compound with the formula C
4H
9O
2CCH=CH
2. A colorless liquid, it is the butyl ester of acrylic acid. It is used commercially on a large scale as a precursor to poly(butyl acrylate). Especially as copolymers, such materials are used in paints, sealants, coatings, adhesives, fuel, textiles, plastics, and caulk.[4]
Butyl acrylate can be produced by the acid-catalyzed esterification of acrylic acid with butanol. Tt polymerizes easily, therefore, commercial preparations contain a polymerization inhibitors such as hydroquinone, phenothiazine, or hydroquinone ethyl ether.[3][4]
Butyl acrylate is of low acute toxicity with an LD50 (rat) of 3143 mg/kg.[4]
In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione; this detoxification produces acrylic acid, butanol, and mercapturic acid waste, which is excreted.[5][6][7]
Exposure can occur through inhalation, skin and/or eye contact absorption, and ingestion.[8] Symptoms may be dependent on exposure route, with skin and eye contact manifesting in redness, pain, and sensitivity; inhalation resulting in burning sensations, cough, shortness of breath, and sore throat; and ingestion resulting in abdominal pain, nausea, vomiting, and diarrhoea.[8]
