Catalytic Acylation of Ethylidenecyclohexane over Zeolite Catalysts
摘要:
Some environmentally friendly catalysts such as HY and H-U zeolites, various cation-exchanged U zeolites, and some other solids have been used in the acylation reaction of ethylidenecyclohexane with acetic anhydride at room temperature to synthesize 3-(1-cyclohexenyl)-2-butanone instead of conventional catalysts. The effect of the amount of HY zeolite used on the acylation reaction was investigated. The yield of the acylated product was 72% in the case of n (ethylidenecyclohexane):n(acetic anhydride):m(HY zeolite)=1 mmol:10 mmol:0.100 g, reaction temperature:25℃, and reaction time:2 h. The regenerated HY zeolite showed almost the same catalytic activity as the fresh zeolite.
