Participants

Reaction Steps

45.2 g (0.1 mol) of 2,2-bis-(3'-tert.butyl-4'-hydroxyphenyl)-cyclohexanepropionic acid are dissolved in ethanol and neutralizaed with an ethanolic solution of 5.7 g (0.1 mol) of potassium hydroxide. The solution is concentrated nearly to dryness, taken up in 250 ml of toluene and mixed with 33.3 g (0.1 mol) of octadecyl bromide. The batch is refluxed for 3 hours, filtered off from the precipitated KBr and concentrated to about 100 ml. The product precipitated after some time is recrystallized from toluene/heptane. Yield 50 g, which corresponds to 71 % of the theory. Melting point 155° C.
