実験手順

172 g (1.15 mol) of 4-tert.-butylphenol, 57.5 g (0.25 mol) of 2,2-bis-(4-hydroxyphenyl)-propane and 20 g of an ion exchanger are heated with stirring for 5 hours to about 170° C. in an autoclave. The ion exchanger is then filtered off while still hot, leaving 208.5 g of a reaction mixture from which 16.7 g (0.088 mol) of 5-hydroxy-1,1,3,3-tetramethyl indane are isolated by fractional distillation.

後処理

  1. filtrationThe ion exchanger is then filtered off while still hot,
