Main uses and manufacturing methods of p-tert-octylphenol

1. Main uses of p-tert-octylphenol
p-tert-octylphenol is a raw material and intermediate of fine chemical industry, such as the synthesis of octyl phenol formaldehyde resin, widely used in oil additives, ink, cable insulation materials, printing ink, paint, adhesive, light stabilizer and other production fields. Synthesis of non – ionic surfactant, widely used in detergent, pesticide emulsifier, textile dye and other products. Synthetic rubber auxiliaries are indispensable for the production of radial tires.

2. Manufacturing method of p-tert-octylphenol
The reaction temperature of phenol and diisobutene was 80℃, and the catalyst was cation exchange resin. The reaction products were mainly p-teroctylphenol, the yield was more than 87%, and p-tert-octylphenol and p-diteroctylphenol were also formed, and the purity of p-teroctylphenol was more than 98% after distillation and purification. The raw material diisobutylene was obtained by isobutylene oligomerization.
