Chromium Fractionation in the Process of Isogydrical Crystalization of Menadione Sodium Bisulfite (Sodium 2-Methyl-1,4-Dioxo-1,2,3,4-Tetrahydro-2-Naphthalenesulfonate)

An improved technology for the industrial production of K3 series vitamins based on menadion is reported. The procedure involves the Cr(VI)-promoted oxidation of the corresponding methyl-naphtahelenes with the following purification by precipitation/recrystallization. The best results were obtained under the process temperature between 20-40 °C, solution pH after dilution of MNB in a range of 5.5–5.7, and MNB content in initial solution of 25-30%.
