A comparison of the catalytic hydrogenation of 2-amylanthraquinone and 2-ethylanthraquinone over a Pd/Al

Enxian Yuan, Xiangwei Ren, Li Wang, Wentao Zhao

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 2,   Pages 177-184 doi: 10.1007/s11705-016-1604-0

Abstract: The hydrogenation of 2-ethylanthraquinone (eAQ), 2- -amylanthraquinone (taAQ) and their mixtures with molar ratios of 1:1 and 1:2 to the corresponding hydroquinones (eAQH and taAQH ) were studied over a Pd/Al O catalyst in a semi-batch slurry reactor at 60 °C and at 0.3 MPa. Compared to eAQ, TaAQ exhibited a significantly slower hydrogenation rate (about half) but had a higher maximum yield of H O and a smaller amount of degradation products. This can be ascribed to the longer and branched side chain in taAQ, which limits its accessibility to the Pd surface and its diffusion through the pores of the catalyst. Density functional theory calculations showed that it is more difficult for taAQ to adsorb onto a Pd (111) surface than for eAQ. The hydrogenation of the eAQ/taAQ mixtures had the slowest rates, lowest H O yields and the highest amounts of degradation products.
