Yield: 98%

Reaction Conditions:

Pt on carbon in water

Steps:

1 Example 1
Example 1 Preparation of 4-butylamino-2,2,6,6-tetramethylpiperidine 776.2 g (5 mol) of molten 2,2,6,6-tetramethyl-4-piperidone (temperature about 40°C) are introduced into a 2 litre autoclave and 402.3 g (5.5 mol) of butylamine are added with stirring, while maintaining the temperature at 30-40°C. 5 g of 5 % Pt on carbon, containing 50 % of water, are then added, and the hydrogenation is carried out at 70-80°C under a hydrogen pressure of 50 bar, until absorption ceases (4 hours). After cooling to ambient temperature, the catalyst is removed by filtration and the 4-butylamino-2,2,6,6-tetramethyl-4-piperidine is separated off by distillation. Boiling point: 154-156°C/66 mbar. Yield: 98 % relative to 2,2,6,6-tetramethyl-4-piperidone.
