A Highly Efficient Cu/Al(OH)3 Catalyst for the Hydration of Acrylonitrile to Acrylamide

A highly efficient, easily filterable Cu/Al(OH)(3) catalyst for the hydration of acrylonitrile to acrylamide has been synthesized by reducing a particle-size-controlled malachite phase-free Cu/Al hydrotalcite. The stability of the Cu/Al(OH)(3) catalyst under aqueous reaction conditions was further improved by treatment with H3PO4.
