“…These peak assignments were consistent with those reported for other similar materials previously. [46,47] Similarly, the XPS spectrum of catalyst SBA-AP-Pd-DT showed a peak at 399.4 eV corresponding to N1s, and a peak at 531.7 eV and a shoulder at 534.7 eV, which correspond to O1s. In addition, the spectrum showed peaks at 337.4 and 342.8 eV corresponding to 3d 5/2 and 3d 3/2 , respectively.…”

We report on the synthesis and catalytic properties of a class of hybrid organic-inorganic mesoporous bifunctional heterogeneous catalysts for efficient catalysis of two-step tandem reactions in one pot. With a solvent-assisted grafting method, two different catalytic groups, that is, an organoamine and a palladium-organodiamine complex, were immobilized onto high-surface-area mesoporous silica sequentially, by using their corresponding organosilanes in 2-propanol or toluene as the solvent in the first step and toluene as the solvent in the second step. Both MCM-41 and SBA-15 mesoporous silicas were used as support materials for the two catalytic groups, and the effect of different sequential grafting of the two organosilanes in 2-propanol or toluene on the structures and the catalytic properties of the resulting bifunctional catalysts were investigated. By using the resulting amine/Pd IIdiamine bifunctional mesoporous material as catalyst, the occurrence of two very important C-C bond forming reactions,

“…The presence of epoxy groups allows a number of chemical modifications on the initial polymer to suit a variety of applications. Consequently, preparation of GMA-based copolymers and their modifications is the subject of numerous papers [10][11][12][13][14][15][16][17][18][19][20][21][22]. The conducted studies had indicated that an amine group is one of the most efficient functional groups for heavy metal ion removal.…”

The porous copolymers of glycidyl methacrylate crosslinked with trimethylolpropane trimethacrylate were prepared in the form of regular microspheres by suspension-emulsion polymerization. In order to obtain adsorbents bearing functional groups, the porous methacrylate network was modified by subsequent reaction with diethylenetriamine. The thermal behavior of the obtained material was studied using TG and DSC. It was found that the process of modification considerably changed the textural and thermal properties of the polymers.

Porous microspheres of glycidyl methacrylate(GMA) cross-linked with trimethylolpropane trimethacrylate (TRIM) were prepared with toluene as porogen by suspension-emulsion polymerization. In order to obtain adsorbents bearing functional groups, the porous methacrylate network was modified by subsequent reaction with pyrrolidone. The thermal behavior of the obtained material was studied using TG and DSC. It was found that the process of modification considerably changed the textural and thermal properties of the polymers.
