4-tert-Butylbenzoic acid is obtained by the liquid-phase air oxidation of 4-tert-butyltoluene (prepared from toluene and isobutylene). It is a modifier for alkyd resins and a polymerization regulator for polyesters. It is also used as an additive in cutting oils and as a corrosion inhibitor. It is hydrogenated to afford the fragrance 4- tert-butylbenzaldehyde.
white to slightly yellow flakes
Corrosion inhibitor in cooling fluids
4-tert-Butylbenzoic acid was used as a potent yeast sirtuin (Sir2p) inhibitor.
ChEBI: 4-t-Butylbenzoic acid is an alkylbenzene.
4-tert-Butylbenzoic acid was determined in water samples by means of liquid chromatography-electrospray ionisation mass spectrometry (LC-ESI-MS).
Flammability and Explosibility
Non flammable
Moderately toxic by
ingestion. Experimental reproductive
effects. An irritant. Combustible when
exposed to heat or flame. Incompatible with
oxidzing materials. To fight fire, use foam,
CO2, dry chemical. When heated to
decomposition it emits acrid smoke and
irritating fumes.
