Reaction Conditions

Reaction Steps

Variant a): In a stirred vessel, 21 l of 20% strength sulfuric acid and 6 kg (60 mol) of acetylacetone were initially charged. The mixture was cooled to about 17° C. and, at 15-20° C., 4.2 kg (60.84 mol) of 40.5% strength aqueous sodium nitrite solution were metered in. The mixture was subsequently stirred at about 17° C. for another 20 minutes and then extracted with 25 l of ethyl acetate. The organic phase was concentrated under reduced pressure, giving 7.42 kg (96% yield) of the title compound.
