Green and Efficient Acquirement of Unsaturated Ether from Direct and Selective Hydrogenation Coupling Unsaturated Aldehyde with Alcohol by Bi-Functional Al-Ni-P Heterogeneous Catalysts

Abstract: In view of the industrial importance of high-grade unsaturated ether (UE) and the inconvenience of acquiring the compound, herein, a series of low-cost Al-Ni-P catalysts in robust AlPO4/Ni2P structure possessing novel bi-functional catalytic features (hydrogenation activation and acid catalysis) were innovated, and testified to be efficient for directly synthesizing UE with a superior yield up to 97% from the selective hydrogenation coupling carbonyl of unsaturated aldehyde (cinnamaldehyde or citral) with C1–C… Show more

“…There is a possibility to synthesize UE via the hydrogenation coupling of unsaturated aldehyde (UA) with alcohol [19,20]. Chen and coworkers [21] performed a study on the green and efficient synthesis of unsaturated ether from direct and selective hydrogenation coupling of unsaturated aldehyde with alcohol over bi-functional (hydrogenation activation and acid catalysis) Al-Ni-P heterogeneous catalysts. The authors noted that the bi-functional Al-Ni-P catalysts were efficient in the direct synthesis of UE (yield = 97%) from the selective hydrogenation coupling carbonyl of cinnamaldehyde or citral with C 1 -C 5 primary or secondary alcohol at 0.1 MPa H 2 pressure and 120 • C. It is believed that such a UE synthesis strategy possesses several integrated advantages (e.g., high efficiency, green manner, and convenient operation), which would provide a potential for feasibly harvesting high-grade UE in the related synthesis of fine chemicals.…”
