摘要：

The oxidation of dithizone with hydrogen peroxide in strongly alkaline solutions yields 1,5-diphenylformazan-3-sulphonic acid as a violet compound which loses a proton to give yellow solutions of the corresponding sulphonate ion and reddish-violet solutions on removal of a second proton from an imino-group. The acid dissociation constants pK1 = -0.92 and pK2 = 12.9 (μ = 1 MNaNO3) were determined spectrophotometrically. © 1969.
