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

In view of the industrial importance high-grade unsaturated ether (UE) and inconvenience acquiring compound, herein, a series low-cost Al-Ni-P catalysts in robust AlPO4/Ni2P structure possessing novel bi-functional catalytic features (hydrogenation activation acid catalysis) were innovated, testified to be efficient for directly synthesizing UE with superior yield up 97% from selective hydrogenation coupling carbonyl aldehyde (cinnamaldehyde or citral) C1–C5 primary secondary alcohol under 0.1 MPa H2 393 K. The integrated advantages high efficiency, green manner convenient operation present heterogeneous system gave potential feasibly harvesting related fine chemical synthesis networks.
