Support organic polymer

Monolith Column—Porous silica column prepared in situ to completely fill the column tube with a fully porous silica foam skelton. After the organic polymer support is heated off, the silica surface is silylated in place to product bonded-phase surface. Column is high resolution and can be used at high flow rates with relatively low back-pressure (see Chapter 16). [Pg.216]

The chosen polymer support influences the reaction as well. Various polymer supports are described above. Studies of the hydrogenation of 2-propen-2-ol with Pd(0) catalysts showed interesting efficiency and selectivity differences dependant on the polymer resin chosen. Zharmagambetova et al. [16] studied three different organic polymer supports for Pd(0) nanoclusters and compared them to the inorganic A1203. Organic polymers included poly-2-vinlypyridine (PVP), cellulose and styrene-divinyl benzene (STY-DVB) copolymer. The cellulose and STY-DVB... [Pg.316]

Disadvantages of the organic polymer supports are low mechanical durabUity (e.g., in stirred tank reactors), poor heat-transfer properties, and limited thermal sta-bihty (up to max. 150°C). [Pg.233]

Chiral P-amino alcohols can also be used for homogeneous HTR of ketones and are known to be effective for reduction of aromatic ketones [38] but, only few examples of organic polymer-supported ligands have been reported. [Pg.61]
