MOLECULAR DESIGN OF LAYERED ZIRCONIUM PHOSPHONATE CATALYSTS

摘要: ABSTRACT Preparation and characterization of two-dimensional zirconium phosphonate derivatives have been investigated. Two composite phosphonates in single crystal phase also investigated characterized by XRD, 13C-, 31P-MASNMR. These compounds are lamellar structures comprising phosphates or organophosphonates. Each layer consists planes bridged through groups which alternate above below the Zr atom planes, oriented away from basal surfaces a bilayered fashion interlayer region. The catalytic performance over is evaluated hydrolysis ethyl acetate esterification acetic acid. When composed with an acidic function hydrophobic phase, activity showed higher without swelling catalyst reaction media. materials become accessible to any reactant molecule improve hydrophobicity.
