2-Ethylanthraquinone → HCID 22315883, compound

Participants

Reaction Steps

A mixture of 2-ethylanthraquinone (25 Kg, 105.9 mol), NBS (19.1 Kg, 107.3 mol) and benzoyl peroxide (70%, 200 g, 0.58 mol) in CCl4 (˜150L) is stirred at reflux for 1.5 hours. On cooling, the precipitate is collected by filtration and washed on the filter with ethanol, hot water and finally ethanol again. After drying, this may be used without further purification (i.e. recrystallisation from benzene/methanol (1:1)).
