Method for co-producing triacetonamine and isophorone

The invention discloses a method for co-producing triacetonamine and isophorone, and relates to the technical field of compound synthesis. The synthesis method comprises the following steps: adding raw materials acetone, ammonia gas and a basic catalyst into a reaction kettle, stirring and reacting at the reaction temperature of 50-100 DEG C for 4-10 hours to obtain a reaction solution containingtriacetonamine and isophorone, carrying out vacuum rectification, continuously applying front fractions, and separating to obtain the triacetonamine and the isophorone. According to the method, the basic catalyst is adopted to catalyze dehydration condensation of acetone to generate mesityl oxide, and further catalyze themesityl oxide and acetone to generate phorone and isophorone, so that efficient co-production of the triacetonamine and the isophorone is realized; post-treatment is simple, the catalyst can be recycled, and no solid waste salt is generated; and the ratio of reaction raw materials is adjustable, and t
