Metal-Organic Frameworks: Adsorption of Hydrocarbons and Alcohols. Lucier, Victor V. Terskikh, Renlong Zheng, Yining Huang. For the phenylacetylene, scattering data on the fully protiated and single deuteriated on the acetyl chain compounds were collected. At shorter distances from the central molecule, more molecules were found to be parallel than at longer separations, but in all cases the number of perpendicular orientations is far higher than the parallel orientations. ... during which the substrate of ethylbenzene (EB) dehydrogenates to product styrene, and the molecular oxygen re-oxidizes the catalysts yielding water. "Reproduced from" can be substituted with "Adapted from". Zhongqiao Hu, Yifei Chen, and Jianwen Jiang . Metal organic frameworks as catalysts in solvent-free or ionic liquid assisted conditions. For all systems, the highest maximum and at shortest distance was found for C13–C13 (carbon atom of the aliphatic chain) PRDF revealing that the probability of finding the aliphatic chains close to each other is higher than to the ring. The second maxima were found at 10.25, 10.85 and 11.05 Å, respectively. 1. The authors declare no conflict of interest. The formation of styrene on the polynaphthoquinone was observed even at 170 °C. Karel J. Hartlieb, James M. Holcroft, Peyman Z. Moghadam, Nicolaas A. Vermeulen, Mohammed M. Algaradah, Majed S. Nassar, Youssry Y. Botros, Randall Q. Snurr, and J. Fraser Stoddart . At shorter distances, molecules prefer to be parallel and at longer separation the perpendicular orientation is preferred (although parallel molecules may still be present at these separations). The majority of industrial production of styrene follows from the dehydrogenation of ethylbenzene.

Lei-Lei Liu, Cai-Xia Yu, Feng-Ji Ma, Ya-Ru Li, Jing-Jing Han, Lu Lin, Lu-Fang Ma. Two regions within the first coordination sphere, in which the surrounding molecules show different preferable orientations with respect to the central molecule, were found for each liquid. were temperature = 620oC, steam to ethylbenzene mole ratio = 11, and partial pressure of N2 diluent = 0.432 bar. The catalytic activity of cobalt ferrite was compared with that of the traditional hematite based catalyst. During the measurements, the samples were maintained at a temperature of 298 K. Additional measurements were made on each of empty sample cells, the empty diffractometer and a 3.0 mm thick vanadium standard sample. Smart nanoporous metal–organic frameworks by embedding photochromic molecules – state of the art and future perspectives. Such materials are peer reviewed and may be re‐organized for online delivery, but are not copy‐edited or typeset. 10 Inclusion of Thiazyl Radicals in Porous Crystalline Materials.

Guang Yan Du, Jian Shen, Tao Sun, Hong Yuan Sun, Chen Cong Shi, Ai You Hao. For MIL-47, diffraction experiments reveal that styrene is packed inside the pores in a unique, pairwise fashion, resulting in separation factors as high as 4 in favor of styrene. Nikita Y. Gugin, Alexander Virovets, Eugenia Peresypkina, Elena I. Davydova, Alexey Y. Timoshkin. D Denayer. The catalytic tests confirmed that the cobalt ferrite is more active and stable than the traditional hematite catalyst. If you are not the author of this article and you wish to reproduce material from I At short separations the most favoured nearest neighbour geometry is parallel. Finally, MIL-53 is also capable of removing typical impurities like o-xylene or toluene from styrene−ethylbenzene mixtures. For the molecules in perpendicular orientations similar observations are found. Investigation on the ethylbenzene/styrene separation efficiency with ionic liquids in liquid–liquid extraction. 2002). Little, Satyanarayana Bonakala, Samantha Y. Chong, Andrew Stephenson, Linjiang Chen, Feihe Huang, and Andrew I. Cooper . This article is part of the themed collection: For reproduction of material from all other RSC journals and books: For reproduction of material from all other RSC journals. At long distances, for all solvents, the population of perpendicular molecules is dominant compared to parallel, and the Y‐shape arrangement was found for all investigated systems. Ethylbenzene can also enhance the risk of NIHL. The catalytic cycle for ethylbenzene dehydrogenation occurs preferentially in the O2−–Fe3+–O2− octahedral sites compared to the O2−–Co2+–O2− sites. Liquid-phase separation of benzene from saturated aliphatics by adsorption on a copper benzene-1,3,5-tricarboxylate metal-organic framework. Learn more. Data for the two extreme angles (in pink and dark blue) are also presented as an inset for direct comparison. The low-angle XRD, N2 isotherms and TEM images show the formation of the mesoporous MCM-41 support with a high surface area. Eric L. First, Chrysanthos E. Gounaris, and Christodoulos A. Floudas .
