809 Enantioseparation on Helical Poly(phenyl-acetylene)s Bearing Cinchona AlkaloidPendants as Chiral Stationary Phases forHPLC
A series of optically active helical poly(phenylacetylene)s bearing cinchona alkaloid pendant groups was coated on macroporous silica gel to obtain novel chiral packing materials for high-performance liquid chromatography, which could resolve diverse racemic compounds into enantiomers whose chiral recognition abilities were significantly influenced by the macromolecular helicity induced by the alkaloid pendants.

The Ni0.3Cu0.2/2MgO·1/2MgAl2O catalyst (a) showed higher activity than a pure Cu catalyst (b) on the NO–CO reaction after pretreatment in oxidation atmosphere. The alloying of Ni and Cu is effective to suppress the surface oxidation of active metal and a decrease of catalytic activity.
