    摘要: A process for preparing metal aminoformazans by alkaline hydrolysis of the corresponding acylated amino derivates in aqueous medium, is described, the hydrolysis being carried out at from 120.degree. to 170.degree. C. and from 3 to 5 bar in the presence of from 1.5 to 3 mol of an alkali metal hyroxide, based on 1 mol of acylated aminoformazan.
