摘    要:Beak et al1 ] reported that the acylation of ethylidenecyclohexane( EDC) using zincchloride as a catalyst gave 3 -( 1 -cyclohexenyl) -2 -butanone( CHB) in good yield.However,it is pity that they provided only little information about reaction conditions,and no information on comparison of activities of various catalysts. Itis well known thatconventional Zn Cl2 catalyst leads to a great number of environmental pollution,whichcould be mainly overcome by use of the solid catalysts as we have …

Abstract:Some environmentally friendly catalysts such as HY and H-β zeolites,various cation-exchanged β 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.
