| Popis: | The solid-phase thermal and catalytic hydrosilylation of N -vinyl-2-pyrrolidone on the surface of hydride silicas has been studied. It was established that thermal polymerization of N -vinyl-2-pyrrolidone occurs as a side reaction during the thermal hydrosilylation of N -vinyl-2-pyrrolidone. It has also been found that the interaction of silicon hydride groups with water and propan-2-ol, as well as the formation of metallic platinum occur as side reactions during the catalytic hydrosilylation of N -vinyl-2-pyrrolidone on the surface of hydride silicas. Thermal hydrosilylation of N -vinyl-2-pyrrolidone in the absence of a catalyst and solvent is much preferred for the chemical bonding of N -vinyl-2-pyrrolidone in the surface layer of hydride silicas. |
