Beschreibung

Allgemeine Beschreibung

Butyl acetate (BA, n-butyl acetate) is an ester commonly used as an organic solvent in cosmetic and pharmaceutical industries and as a flavoring agent in food industry. One of the methods reported for its synthesis is the esterification reaction between acetic acid and butanol catalyzed by expandable graphite (EG). The decomposition of butyl acetate by photocatalysis in gas phase has been studied using TiO₂, Pt/TiO₂ and WO₃/TiO₂ catalysts. BA is a probable biofuel additive.

Butyl acetate is a butyl ester of acetic acid. It exists in four isomeric forms: butyl acetate, sec-butyl acetate, isobutyl acetate and tert-butyl acetate. It is a colorless pleasant smelling liquid.

Anwendung

Butyl acetate has been used for the preparation of testicular tissue and cell cultures for immunohistochemical (IHC) and immunofluorescent (IF) staining.

Butyl acetate may be used to abstract aluminium-hydroxyquinolate complex from soil extracts for determining aluminium spectrophotometrically and by fluorimetry. It can also be used to abstract traces of gold from ores which is then determined by flame atomic absorption spectrometry.
