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 BA by photocatalysis in the gas phase has been studied using WO₃/TiO₂ (tungsten oxide/titanium dioxide), Pt/TiO₂ and TiO₂ catalysts. BA is a probable biofuel additive.

Anwendung

Meets urethane grade requirements (H2O ≤ 0.05%)
