摘要:In the synthesis of 2,2,6,6-tetramethylpiperidone-4 (triacetone-amine) from acetone and ammonia, a partially halogenated or perhalogenated aliphatic or cyclic hydrocarbon is used as catalyst in an amount of from 0.01 to 5 mol %, relative to acetone.

摘要:An improved method is used for preparing triacetone amine while recycling the by-products. This involves treating the crude product from triacetone amine preparation, which leads to an increase in the content of compounds which react readily with ammonia. This method enables efficient recycling of the by-products formed in the synthesis of triacetone amine.

发明人：MINKE KATHARINA; GRASKAMP HOLGER

摘要:An improved process can be used for preparing triacetonamine. The process involves performing an absorption step in which acetone present in the crude product is removed from triacetonamine by distillation, and in gaseous form is then absorbed in countercurrent into fresh, liquid acetone. The acetone stream thus obtained is then converted further to triacetonamine. This process enables more energy-efficient reutilization of the unreacted reactants used in the synthesis of triacetonamine, and thus lowers overall both the use of reactants and the energy expenditure.
