実験手順

121 g (0.5 mol) of 2,2-bis-(4-hydroxyphenyl)-butane, 22 g of an acid-activated fuller's earth and 90 g (1.6 mol) of isobutylene are stirred in an autoclave for 6 hours at 180° C. After cooling, the reaction mixture is taken up in 150 ml of toluene, the catalyst filtered off and the solvent evaporated. The residue is fractionated through a 1 meter glass-packed column, giving at a boiling temperature of 155° to 160° C./12 Torr 37 g of a fraction from which 24.8 g (20 % of the theoretical) of 5-hydroxy-1,3,3-trimethyl-1-ethyl indane (V) melting at 86° C. are obtained by recrystallisation from 90 ml of petroleum ether. ##STR23##
