How Is it Manufactured?

Methyl 4 tertiary butyl benzoate is synthesized by different methods. It can be produced by the oxidation of a liquid phase solvent like acetic acid. Another method is high-temperature gas-phase oxidation. Here, p-tert-butyl toluene is oxidized at a high temperature in the presence of a catalyst to yield Methyl 4 tert butyl benzoate. It can also be synthesized from p-tert-butyl toluene using nitric acid.

 

Industry Applications

  • Methyl 4 tert butyl benzoate has wide applications in the personal care industry. It helps in producing avobenzone which is a UVA I, UVA II blocker used in sunscreens, hair care products, shampoos and skincare.
  • It is also used in the production of PVC heat stabilizers and as an additive for cutting oil and lubricants.
  • This speciality chemical acts as an alkyd resin modifier to help improve resin properties such as its lustre, colour and performance.
