The continuous synthesis of triacetonamine from acetone and ammonia over HY was realized. Meanwhile, alkali-treated HY with different structure and acidities were prepared and examined. The results indicated that the acid sites, especially Br?nsted acid sites, played a vital role on the selectivity of triacetonamine and the conversion of acetone. It was further confirmed by X-ray diffraction (XRD), N2 adsorption and desorption experiments, IR spectra of adsorbed pyridine, and NH3 temperature-programmed desorption. Meanwhile, the generation mechanisms of triacetonamine and impurities were speculated.

The continuous synthesis of triacetonamine from acetone and ammonia was realized over sulfonic acid-functionalized mesoporous silicas. These catalysts were characterized by TG, XPS, BET, elemental analysis and acid-base titration. The results indicated th
