| titleOfInvention | Method for producing 4-tert-butylphenol |
| abstract | (57) Abstract: When used as a terminal blocking agent for aromatic polycarbonate, the obtained aromatic polycarbonate is not colored and can be suitably used for optical recording media and optical information transmission media. To provide a method for producing PTBP with less impurities. SOLUTION: The content of phenol (a) and isobutylene (b), preferably dialkyl ether, is 100 A method for producing 4-tert-butylphenol, comprising reacting isobutylene (b1) of less than 1 ppm with a pressure of 200 kPa or less, preferably at atmospheric pressure, in the presence of a catalyst. |
