摘要：

Deposited copper hydrosilicates are synthesized using KSKG industrial silica gel. The hydrosilicates are modified with Fe2+ ions. Their catalytic activity and high selectivity in the hydrogenation of dinitrobenzene is shown to yield nitroaniline and phenylenediamine under mild conditions at 170 degrees C and a hydrogen pressure of 1.3 MPa. As an example, C-C triple bond in phenylacetylene is hydrogenated for the first time on such materials using molecular hydrogen under relatively mild conditions.
