HCID 314052,6-Di-tert-butylphenolYield 100%

Procedure

Phenol and the above-mentioned catalyst are charged into a reactor; the mixture is heated to 100°-110° C. and isobutylene is passed thereinto for 8 hours. The resulting alkylate is subjected to a vacuum-rectification. After recrystallization of the product from aliphatic hydrocarbons, a 100% pure 2,6-di-tertbutylphenol is obtained.

Workup

  1. temperaturethe mixture is heated to 100°-110° C.
  2. customAfter recrystallization of the product from aliphatic hydrocarbons
