Dyes and pigments
Also involved in preparation of catechol-derived compounds.
4. Corrosion Inhibitor
Incorporated in lubricants, fuels, and oils as a corrosion-inhibiting antioxidant.
5. Stabilizer for Fuel and Lubricants
Added to fuels, biodiesels, and industrial oils to improve oxidative stability and prevent gum formation.
Benefits
✅ Effective Polymerization Inhibitor
TBC offers long-term stability, even at high temperatures (e.g., 60–100°C), making it superior to hydroquinone in many applications.
✅ Thermal and Oxidative Stability
Resists degradation under heat and oxygen exposure, enhancing the shelf life of monomers and fuels.
✅ Low Volatility and Low Toxicity Profile
Offers safer handling and reduced volatility compared to some other stabilizers like MEHQ (monoethyl hydroquinone).
✅ Versatile Solubility
Soluble in organic solvents, allowing for easy blending into monomer mixtures, oils, and fuels.
✅ Cost-Effective
A reliable and economically favorable choice for industrial-scale use as a stabilizer or antioxidant.
Conclusion
4-tert-Butylcatechol (TBC, CAS 98-29-3) is an essential stabilizing and antioxidant compound used across polymer, rubber, fuel, and chemical synthesis industries. Its excellent thermal and oxidative resistance, combined with its strong inhibitory properties, make it indispensable for preventing unwanted reactions and extending material durability.
