Procedure

Variant c): In parallel, 490 g (2.5 mol) of 50% strength sulfuric acid and 852 g (5 mol) of 40.5% strength strength aqueous sodium nitrite solution were metered into a mixture of 500 g (5 mol) of acetylacetone and 2 l of water, the pH being adjusted to 3.7-4.2 and the temperature to 15-18° C. Work-up as in variant a) gave 588 g of the title compound (91% yield).
