Paragraph 0133-0144, (2020/07/05)
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.

The invention relates to a method for preparing intermediate 2,2,6,6-tetramethyl-4-piperidylamine. The method is characterized by comprising the following steps: step 1), in the presence of a catalyst1, reacting acetone with ammonia gas to produce 2,2,6,6-tetramethyl-4-piperidinone and water; and step 2), in the presence of a catalyst 2, reacting the 2,2,6,6-tetramethyl-4-piperidinone with ammonia gas to produce 2,2,6,6-tetramethyl-4-piperidylimine and water, and reacting the 2,2,6,6-tetramethyl-4-piperidylimine with hydrogen gas to produce the 2,2,6,6-tetramethyl-4-piperidylamine, wherein the catalyst 1 is ammonium nitrate, and the catalyst 2 is a sodium hydroxyphenyl phosphate modified framework nickel catalyst. The method provided by the invention has the advantages of short synthetictime, a high conversion rate of the acetone and a high repeating utilization rate of the raw materials.
