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. It is manufactured from acetic acid and isobutylene. An attempt at Fischer esterification would lead to elimination of tert-butyl alcohol to isobutylene. Butyl acetate has four isomers: "tert"-butyl acetate, "n"-butyl acetate, isobutyl acetate, and "sec"-butyl acetate.
