Procedure

Variant b): 1225 g of 20% strength sulfuric acid were metered into a solution of 500 g (5 mol) of acetylacetone, 1 l of water and 1305 g of 25% strength aqueous sodium nitrite solution, the pH being adjusted to 3-5 and the internal temperature to 25-17° C. The product of value was isolated as in variant a). This gave 570 g of the title compound (89% yield).
