tert-Butyl acetate
tert-Butyl acetate, t-butyl acetate or TBAc is a colorless flammable liquid with a camphor- or blueberry-like smell. It is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners and industrial cleaners. It has recently gained EPA volatile organic compound (VOC) exempt status[3].

It is manufactured from acetic acid and isobutylene.[1] While an attempt at Fischer esterification would lead to elimination of tert-butyl alcohol to isobutylene, it may also be synthesized in the laboratory by the Steglich esterification of acetic acid and tert-butyl alcohol.[4]
Butyl acetate has four isomers: tert-butyl acetate, n-butyl acetate, isobutyl acetate, and sec-butyl acetate.
