General description

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.[16][18] One of the methods reported for its synthesis is the esterification reaction between acetic acid and butanol catalyzed by expandable graphite (EG).[16] The decomposition of butyl acetate by photocatalysis in gas phase has been studied using TiO2, Pt/TiO2 and WO3/TiO2 catalysts.[19] BA is a probable biofuel additive.[44]
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.[71]

Application

Butyl acetate has been used for the preparation of testicular tissue and cell cultures for immunohistochemical (IHC) and immunofluorescent (IF) staining.[72]
Butyl acetate may be used to abstract aluminium-hydroxyquinolate complex from soil extracts for determining aluminium spectrophotometrically and by fluorimetry.[21] It can also be used to abstract traces of gold from ores which is then determined by flame atomic absorption spectrometry.[41]
