Fang, L. published the artcileHighly selective Ru/HBEA catalyst for the direct amination of fatty alcohols with ammonia, COA of Formula: C8H18O, the main research area is ruthenium HBEA catalyst amination fatty alc ammonia.
The present study describes the synthesis of primary amines from long-chain fatty alcs. and ammonia using supported ruthenium catalysts over different acid supports, including a variety of zeolites with different topologies and Si/Al ratios. The morphol., acidity and location of ruthenium in the catalysts was studied in detail by combining XRD, BET, HR-TEM, NH3-TPD, octylamine-TPD, H2-TPR, XPS, EXAFS / XANES, 27Al MAS NMR and TGA. In particular, Ru/HBEA (Si/Al = 25) with 5 wt% Ru afforded more than 90% conversion and 90% selectivity to 1-octylamine in the liquid-phase amination reaction of 1-octanol with ammonia at 180°C in a batch reactor. The high selectivity of Ru/HBEA (Si/Al = 25) can be explained by the presence of Bronsted / Lewis acid centers with medium strength in the proximity of ruthenium nanoparticles. The catalyst was further tested in a pre-pilot continuous stirred-tank reactor (2 L) with flash separation of 1-octylamine. In this configuration, a steady 92% selectivity of octylamine was obtained at 87% 1-octanol conversion during 120 h on steam. The catalyst kept its integrity during the reaction.
