Bisphenol A → 1,1,3,3-Tetramethylindan-5-ol

참여 물질

반응 단계

172.5 g (1.15 mol) of 4-tert.-butylphenol, 57.5 g (0.25 mol) of 2,2-bis-(4-hydroxyphenyl)-propane and 10 g of an acid-activated fuller's earth were heated with stirring in an autoclave for 6 hours to approximately 200° C. The hot reaction mixture is then filtered off from the catalyst under suction and the resulting 221.3 g reaction mixture subjected to fractional distillation in vacuo, giving 25.2 g (52 % of the theoretical) of 5-hydroxy-1,1,3,3-tetramethyl indane.
