| titleOfInvention | Method for producing zirconium oxide catalyst and orthoalkyl compound |
| abstract | (57) [Problem] To provide a zirconium oxide catalyst excellent in selectivity for producing an orthoalkylphenol compound. The present invention relates to a catalyst for producing an orthoalkylphenol compound by using a phenol compound having at least one hydrogen atom at the ortho position and an alcohol, having a BET specific surface area of 0.1 to 40 m 2 / g and an acid / base strength. It is a zirconium oxide catalyst characterized by satisfying +1.5 <H 0 <+12.2. The precursor containing a zirconium source can be prepared by firing at 800 to 1200 ° C. The use of the catalyst of the present invention enables the alkylation reaction to be carried out with high selectivity, particularly in the supercritical region or subcritical region. |
