CATALYST FOR PREPARING 2,4-DITERTIARY BUTYLPHENOL AND METHOD FOR PREPARING 2,4-DITERTIARY BUTYLPHENOL USING THE SAME

摘要

PURPOSE: Provided are a catalyst for preparing 2,4-ditertiary butylphenol from phenol and isobutylene, and a method for preparing 2,4-ditertiary butylphenol using the same. CONSTITUTION: In a method for preparing 2,4-ditertiary butylphenol by addition reaction of isobutylene to phenol in the presence of a catalyst, the catalyst is fabricated by calcining activated clay including 1 to 40 wt.% of -aluminum hydroxide or amorphous silica, wherein the -aluminum hydroxide is pseudo-boehmite; the amorphous silica is colloid silica; and the phenol is phenol compounds selected from 2-tertiary butyl phenol or 4-tertiary butyl phenol.
