Chemical Properties Of 2,6-Di-Tert-Butylphenol CAS 128-39-2

  • 2,6-Di-tert-butylphenol (2,6-DTBP) serves as the starting material in the production of the most efficient phenolic antioxidants known today and also for the synthesis of 4,4′-dihydroxybiphenyl. The compound is usually synthesised by the alkylation of phenol or of 2-tert-butylphenol (2-TBP) with isobutene. In the presence of aluminium tris-(phenolate) catalyst temperatures between 100 and 125 °C and at pressures up to 25 bar have been employed.
  • Colorless crystalline block with phenol odor. Solubility in water is 2.3% at 40℃ and 5% at 100℃. Soluble in caustic soda and common organic solvents.
