Методика

Inoue et al (Chem. Pharm. Bull., 24 (9), 2199-2203, 1976) disclose ferric oxide and chromium oxide to be new alkylating catalyst of phenols. The activity and selectivity of these oxide catalysts were examined by liquid-phase reaction. 1-Naphthol, methanol and ferric oxide were charged in an autoclave equipped with a magnetic stirrer. After air in the autoclave was replaced by hydrogen, the temperature was raised to 400° C. over a period of 45 to 50 minutes. At such temperature, the pressure reached 100 atm. After 3 hours. 2-methyl-1-naphthol was produced in a conversion of 57.6 mol %. The remainder was starting material.
