Conditions

Temperature: 50 °C

Procedure

760 g 1,1,3,3-tetramethyl-5-hydroxy-indane, 2000 g tripropylene and 10 ml borofluoride-etherate are stirred for 1.5 hours at 20° to 25° C whilst being cooled with water. Then 30 g white-lime hydrate are added and stirred for 1 hour at 50° C. The reaction mixture is removed from the lime and the excess tripropylene is distilled off in a water stream vacuum to an absorbtion temperature of 150° C. The residue consists of 1268 g 1,1,3,3-tetramethyl-6-isononyl-5-hydroxy-indane in the form of a yellowish viscous oil.
