A new route to functional polymers: Synthesis of functional polymer-supported esters from a weak acid ion exchange resin

The Functionality of Ion Exchange Resins for Esterification, Transesterification and Hydrogenation Reactions

“…Differences between ion exchange and adsorption process [12] Ion exchange Adsorption sorbed species are ions sorbed species are electrically neutral substances removed from liquid phase and substituted by ions from the solid phase removal process only cannot be described by only diffusion equation due to the fluxes of at least two different ions being coupled together can be described by diffusion equation to be adsorb on and post-adsorption which allows for reduction of the metallic species, thereby creating a platform for the nanoparticles to be dispersed uniformly. [21][22][23] The polymeric platform which serves as a solid stabilizer stops the particles from agglomerating, hence, increasing the activity of catalyst and eliminating high temperature for the calcination step required by most catalyst. This is due to the strong bond existing between the functional groups which improves interaction between the polymer structure and the metal (minimizing leaching) and allows for variations of metallic loading by adjusting the uptake of the metal precursor by the ion exchange resin.…”

“…In comparison to activated carbon and alumina which have been extensively reported in literature by Wang, functional polymeric resins offer several advantages such as possess uniformly dispersed functional groups allowing ions (precursor) to be adsorb on and post‐adsorption which allows for reduction of the metallic species, thereby creating a platform for the nanoparticles to be dispersed uniformly . The polymeric platform which serves as a solid stabilizer stops the particles from agglomerating, hence, increasing the activity of catalyst and eliminating high temperature for the calcination step required by most catalyst.…”

Synthesis of 8-hydroxyquinoline-Amberlite IRC-50 chelator for solid phase extraction of trace metals from groundwater samples

“…The Amberlite IRC-50 resin is a weak acidic cation exchanger consisting of methacrylic acid-divinylbenzene copolymer with carboxylic function groups. It commercialized as white opaque beads of 16-50 mesh (0.33-0.50 mm) and occasionally it contains 43-53% of moisture [37]. Extensive literature survey shows that most of the earlier chemical modifications reported for Amberlite IRC-50 have been carried out through carboxylic acid group, whereby the acid is converted into chlorocarboxylate resin by chlorinating agent to facilitate ligand coupling [38,39].…”
