Reaction Steps
A solution of 337.5 g (0.75 mol) of N,N′-bis-[2,2,6,6-tetra-methylpiperidin-4-yl]-N,N′-bisformyl-1,6-diaminohexane in 600 ml of methanol was treated with 0.15 g of MgSO4. 600 ml of a 30% strength H2O2 solution (5.87 mol) were added dropwise at 67° C. in the course of 6 h. The temperature was then increased to 81° C. and the mixture was kept at this temperature for a further 6 h, the pH of 7.8 being kept constant by metered addition of a 50% strength KOH solution. The pH was then adjusted to 9.0 by addition of KOH solution. After the mixture had been left at this pH for a further 2 h, the methanol was distilled off, the product being precipitated. It was washed with water and dried.
