Description

General description

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. Its photocatalytic decomposition has been carried out in a fixed-bed continuous annular reactor in the presence of Pt/TiO2and WO3/TiO2 catalysts.
