Two silica-supported dendrimers containing ruthenium nanoparticles (S-D/RuNPs) have been synthesized through the divergent method and characterized by the attenuated total reflectance-IR (ATR-IR), field-emission SEM (FE-SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and inductively coupled plasma (ICP) techniques. To prepare S-D/RuNPs, a first-generation dendrimer was synthesized from hexakis(bromomethyl)benzene (hex) core and vanillin branches. In the next step, second-generation dendrimers, hexpyD and hexbzaD, were synthesized by the reaction of the first-generation dendrimer with ortho-aminopyridine (py) and para-aminobenzoic acid (bza), resp. The second-generation dendrimers, hexpyD and hexbzaD, were then reacted with ruthenium(III) chloride to form the hexanuclear Ru(III) complexes which were immobilized on a silica support and reduced by NaBH4 in 2-methoxyethanol as the solvent. The mean size of the ruthenium nanoparticles encapsulated within the dendrimers was found to be 2 and 6 nm in hexpyD and hexbzaD, resp. In addition, the catalytic activity of the synthesized nanoparticles were investigated on the hydrogenation of citral (3,7-dimethyl-2,6-octadienal) to 3,7-dimethyloctanol. The effect of S-D/RuNPs catalysts on the hydrogenation reaction was monitored by gas chromatog.-mass spectrometry (GC/MS). The results revealed that the increase of the reaction temperature and reaction time leads to a higher reaction yield at a constant pressure. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8HPLC of Formula: 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.HPLC of Formula: 106-21-8
