| abstract |
(57) [Summary] [Structure] Ammonia is reacted with at least one selected from acetone and a condensate of acetone in the presence of a magnesium-aluminum composite compound. 2,6,6-tetramethyl-4-oxopiperidine and / or 2, A method for producing 2,4,4,6-pentamethyl-2,3,4,5-tetrahydropyrimidine. [Effect] According to the method of the present invention, TAA And / or ACN can be efficiently produced. In addition, the present invention is industrially advantageous because the catalyst can be easily removed. |
