Applications:


4-Tert-butylbenzoic acid is added as a stabilizer or modifier for alkyd resin and as a corrosion inhibitor in cooling fluids. Because of the sterically hindered group, tert-butyl aromatic compounds have an antioxidizing action and also act as UV stabilizers. It is used as an intermediate of organic target substances and also used as a fixative of fragrance.

PTBBA is also used as process regulator (chain stop agent) in polymers industry for producing alkyd and polyester resins. PTBBA is added into the polymerization step of resin production where it reacts covalently with the usual alkyd monomers.
