“…The GMA gels after their chemical modification in the reaction with polyamines become capable to coordinate different transition metals, including palladium. The last feature was used previously for preparation of the polymer supported palladium catalysts for the hydrogenation of substituted olefins and acetylenes [38,39]. The catalysts based on the resin cross-linked with diethylene glycol dimethacrylate (DEGDMA), bearing EDA units, turned out to be efficient in the hydrogenation of 2-butyne-1,4-diol and phenylacetylene.…”

“…It has been established that ion resins are employed for hydrogenation reaction by using a functional metallic catalyst. [86,87] Metal movement from the polymer material to the interior of the pores takes place during catalyst reduction in the swelling medium. [27] The ease with which the metal accesses the pores is largely factored by the surface area of the pore coupled with the matrix of the ionic resin polymer.…”

Ion exchange resins (IER) possess a catalytically flexible structure which enables them to be easily applied for renewable energy production and environmentally friendly reactions. More specifically, they can be used as catalyst or catalyst support in other industrialized processes such as; esterification, transesterification and hydrogenation reactions. Several works on esterification, transesterification and hydrogenation reactions are in literature. This study reviews some of these works which includes the utilization of IER in esterification, trans-esterification and hydrogenation reactions. Recent reports show that IER are conventionally used as catalyst in esterification and transesterification reactions. For hydrogenation reactions, IER have been utilized as support for metallic catalyst, raising questions on their inability to be applied as catalyst. Hence, this study has itemized these various reactions, detailing their applications which are highly industrialized reaction processes.

“…The FCN resin (3% crosslinking degree) (77 wt% styrene, 2.78 wt% N content) [28] swells very well in THF and this solvent is used as a medium during the preparation of Ru-composites (1, 2 and 4 wt% Ru) according to the previously described procedure [30]. Thus, FCN resin preswollen in THF is treated with appropriate amount of aqueous solution of RuCl 3 under slow mixing up to the complete incorporation of ruthenium species.…”

“…Moreover, our preliminary catalytic data demonstrate the advantage of biphasic IO/H 2 O solvent system in hydrogenation of ACT in the presence of Ru-catalysts supported on methacrylate-styrene gel-type resin (FCN) (Scheme 2). The FCN polymer is functionalized with C=O, -NH, and -NH 2 groups and is used for the preparation of palladium catalysts with finely dispersed Pdnanoparticles [28,29]. Our previous results show that functional groups of FCN resin, and in particular the Ncontaining ones participate in the bonding of Pd, Ruspecies via filling metal coordination sphere [28][29][30].…”

Hydrogenation of Acetophenone in the Presence of Ru Catalysts Supported on Amine Groups Functionalized Polymer

Liquid phase hydrogenation of acetophenone (ACT) is studied over ruthenium catalysts (1-4 wt% Ru) supported on gel-type methacrylate-styrene resin (FCN) functionalized with C=O, -NH, and -NH 2 groups. Microscopic studies (SEM, STEM) show that the nature of Ru particles depends on the level of Ru doping. At low Ru content (1-2 wt%) ruthenium nano-clusters are formed, while at 4 wt% Ru, metal crystallites of few nanometers in size are observed. Catalytic reactions are performed at mild conditions (atmospheric pressure of hydrogen, 40°C) in biphasic isooctane-water (IO/H 2 O) solvent system, and, for comparison, in a single component solvent (isooctane or ethanol). The use of biphasic IO/H 2 O solvent system results in a dramatic improvement of selectivity. The hydrogenation of C=O in acetophenone dominates over the hydrogenation of aromatic ring, yielding 1-phenylethanol with ca. 80% selectivity. Ru/FCN catalysts exhibit higher selectivity than the reference Ru/Al 2 O 3 . This is tentatively assigned to the steric effects induced by the polymer network on migrating reactant molecules. Advantageous influence of biphasic IO/H 2 O solvent system has been attributed to the solvation of phenyl ring of acetophenone by non-polar isooctane, which facilitates the interaction with the catalyst surface via carbonyl group and leads to the preferential reduction to 1-phnenylethanol.
