It is manufactured from acetic acid and isobutylene.[1] An attempt at Fischer esterification would lead to elimination of tert-butyl alcohol to isobutylene.
Butyl acetate has four isomers (or five, including stereoisomers): tert-butyl acetate, n-butyl acetate, isobutyl acetate, and sec-butyl acetate (two enantiomers).
