Bisphenol A → 5-Hydroxy-1,1,3-trimethyl-3-neopentyl indane

Participants

Reaction Steps

57 g (0.25 mol) of 2,2-bis-(4-hydroxyphenyl)-propane, 10 g of an acid-activated fuller's earth and 84 g (0.75 mol) of diisobutylene are stirred in an autoclave for 8 hours at around 150° C. The catalyst is then filtered off and the reaction mixture subjected to fractional distillation, giving 25.2 g (44% of the theoretical) of 5-hydroxy-1,1,3-trimethyl-3-neopentyl indane.
