Abstract
A new spectrophotometric method for determination of diacetyl has been developed. This method make use of the abili ty of diacetyl to react with isoniazid forming diacetyl diisonicotin hydrazone. This hydrazone then complexes Zr (IV) at acid pH (1,7) giving rise to a yellow and soluble chelate. The molar absorptivity is 1,7.104 l mol-1 cm-1. Themethodhas been applied tothemeasure of diacetyl in butter.
