4-tert-Butylbenzoic acid is a colorless needle shaped crystal or crystalline powder, and is an important intermediate in organic synthesis. P-tert butylbenzoic acid is mainly used in the production of alkyd resin modifiers, cutting oil, lubricating oil additives, polypropylene nucleating agents, and stabilizers. Using p-tert butylbenzoic acid to modify alkyd resin in Chemicalbook can improve the initial gloss, enhance the durability of color tone and gloss, accelerate drying time, and have excellent resistance to chemicals and soapy water. Using this amine salt as an oil additive can improve working performance and rust prevention. When used as a stabilizer, its barium salt, sodium salt, zinc salt, etc.
