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 that both the acidity and the textural properties of the catalysts had significant influences on the catalytic performance. Meanwhile, the effects of reaction parameters on the reaction of acetone and ammonia were investigated. Based on the experimental results, the reaction mechanisms were speculated.
