Procedure

112 g of isobutylene were introduced with stirring into 198 g of 1-phenyl-1-(4-hydroxy-phenyl)-ethane and 30 g of an acid activated Fuller's earth at 150° C. and the reaction mixture was then stirred at this temperature for 5 hours. 34 g of 1,3,3-trimethyl-1-phenyl-5-hydroxy-indane could be obtained by distillation followed by recrystallisation.
