Abstract
Silica-supported palladium complexes of the bipolymers chitosan-polyac rylic acid and chitosan-polymethachrylic acid were shown to have a hig her activity in the proper molar ratio of monomeric units of chitosan to polyacrylic acid or polymethacrylic acid in the hydrogenation of ni trobenzene to aniline or acrylic acid to propionic acid at room temper ature and under atmospheric pressure. Such palladium complexes of bipo lymers are very active, selective and stable in the hydrogenation. In the hydrogenation of acrylic acid to propionic acid, the turnover numb ers were > 14000 in 4-6 h, and no by-products were observed.
