Vorschrift

A mixture of 155 g of triacetone amine, 113 g of diethylene triamine, and 2.5 g of conc. sulfuric acid in 2.5 liters of methanol is hydrogenated in the presence of 7 g of 5% palladium on carbon in the manner described in Example 1. In addition to yielding 1,7-bis(2,2,6,6-tetramethyl-4-piperidyl)-1,4,7-triazaheptane, distillation of the hydrogenation mixture yields at 115°-118° C./0.09 mm Hg 1-(2,2,6,6-tetramethyl-4-piperidyl)-1,4,7-triazaheptane as main product.
