Versuchsvorschrift
For example, U.S. Pat. No. 2,831,898 discloses a process for producing 2,6-diisopropyl phenol from propylene gas and phenol by Friedel-Crafts reaction at high pressure of 21-35 atm, high temperature of 200°-210° C. and under nitrogen atmosphere with aluminum phenoxide, as a catalyst, prepared from alumina and phenol. But there is a defect that 2,6-diisopropyl phenol desired was obtained only with 11.3% yield even though 2-isopropyl phenol which is a by-product was obtained with 31.4% yield.
