Descrizione

Descrizione generale

Butyl acetate can find wide applications in painting and coating industries.[1] It can also serve as a substitute to toxic solvents used in the manufacture of acrylic polymers, enamels, vinyl resins, nitrocellulose and lacquers.[1] It is generally prepared by the esterification of butanol with acetic acid in the presence of sulfuric acid.[1] It can also be obtained via transesterification reaction of methyl acetate with butanol.[1]

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.
