Uses
Intermediate in organic synthesis, polymers and copolymers for solvent coatings, adhesives, paints, binders, emulsifiers.
Butyl Acrylate is used to make polymersthat are used as resins for textile and leatherfinishes, and in paints.
Butyl acrylate is primarily used as a reactive building block to produce coatings and inks,adhesives, sealants, textiles, plastics and elastomers.
Butyl acrylate is used in the following applications:
Adhesives – for use in construction and pressure-sensitive adhesives
Chemical intermediates – for a variety of chemical products
Coatings – for textiles and adhesives, and for surface and water-based coatings, and coatings used for paints, leather finishing and paper
Leather – to produce different finishes, particularly nubuck and suede
Plastics – for the manufacture of a variety of plastics
Textiles – in the manufacture of both woven and non-woven textiles
Butyl acrylate is primarily used in the production of homopolymers and co-polymers for use in water based industrial and architectural paints.
Butyl Acrylate can also be used in cleaning products, antioxidant agents, enamels, adhesives, textiles, caulks and paper finishes.
The double bond reactivity also allows for Butyl Acrylate to be used as a chemical intermediary.
The primary end user markets of this product would be the water, plastics, leathers, paints, adhesives and textiles industries.
Production and properties
Butyl acrylate can be produced by the acid-catalyzed esterification of acrylic acid with butanol.
Butyl Acrylate polymerizes easily, therefore commercial preparations contain polymerization inhibitors such as hydroquinone, phenothiazine, or hydroquinone ethyl ether.
Butyl Acrylate can be manufactured via a reaction of acetylene, n-butyl alcohol, carbon monoxide, nickel carbonyl, and hydrochloric acid.
Butyl Acrylate is commonly manufactured via an oxidation of propylene to acrolein and then to acrylic acid.
The acid is reacted with n-butanol to yield the butyl ester.
Hazard
Moderate fire risk.
Questionable carcinogen.
Acrylic esters, including butyl acrylate, have a very strong, unpleasant odor that may be bothersome.
However, the smell of acrylates does not necessarily indicate a health risk.
Acrylic esters have an extremely low odor “threshold,” meaning that even very small amounts in the air can be detected by smell.
Butyl acrylate liquid and vapors may cause slight eye irritation and even slight corneal damage.
They may also cause pain greater than expected given the level of irritation.
Brief contact may cause moderate skin irritation with local redness.
Prolonged contact may cause severe skin irritation with local redness and discomfort.
Prolonged or widespread skin contact may result in absorption of harmful amounts and may cause an allergic skin reaction.
Excessive exposure to butyl acrylate vapors may cause irritation to upper respiratory tract (nose and throat) and lungs.
Vapor concentrations are attainable which could be hazardous on single exposure.
Butyl acrylate has low toxicity if swallowed, but may result in gastrointestinal irritation or ulceration.
Swallowing butyl acrylate may result in burns of the mouth and throat.
Butyl acrylate causes birth defects in laboratory animals only at doses toxic to the mother.
Butyl Acrylate is toxic to the fetus in lab animals at doses toxic to the mother.
