| Abstract: | The intermediate 2,3-dihydrofuran was prepared in high yield with good selectivity using2,5-dihydrofuran as raw material,N,N-diethylhydroxylamine as a polymerization inhibitor,under pressure reaction catalyzed by carbonyl tris(triphenylphosphine)ruthenium.Then,2,3-dihydrofuran was efficiently isomerized to cyclopropanaldehyde in a fixed-bed process catalyzed by the nano-catalyst ZrO2/TiO2/γ-acidic alumina.The total yield of the two-step reaction is over 75.0%.The industrial production methods of cyclopropanaldehyde were studied.The effects of various rare metal catalysts,reaction temperature,pressure,and the type and amount of polymerization inhibitors on the synthesis of 2,3-dihydrofuran were investigated,Similarly,the effects of reaction temperature of the fixed-bed catalytic process and composite of catalysts on the synthesis of cyclopropanaldehyde have also been investigated.With the advantages of green and high efficiency,this process has broad market prospects. |
