Procedure
To 470 g of phenol and 100 g of an acid-activated fuller's earth 1020 g of cyclopentene are added dropwise at 140° C whereupon the mixture is stirred at the same temperature for 15 h. After elimination of the catalyst by filtration the reaction mixture is distilled by fractionation. Besides 2,4,6-tricyclopentylphenol 173 g of a fraction are obtained having a boiling range of 205° to 212° C at 1.4 mm Hg which are recrystallised from ligroin. Yield: 143 g of 2,4,5-tricyclopentylphenol. Melting point: 104° C.
