Choi, Byeong-Min; Son, Seok-Hwan; Lee, Chul-Wee; Park, Sun-Yeong; Chung, Min-Chul published the article 《Characterization and synthesis of molybdenum metal precursors for hydrocracking reaction of vacuum residues》. Keywords: molybdenum metal hydrocracking reaction.They researched the compound: 1,2-Bis(diphenylphosphino)ethane( cas:1663-45-2 ).HPLC of Formula: 1663-45-2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1663-45-2) here.
In this study, Molybdenum precursors were synthesized with Triphenylphosphine, 1,2-Bis(diphenylphosphino)ethane, Pyridine, 2,2-Bipyricine as a ligands. The molybdenum precursors was used for Hydrocraking reaction of Vacuum Residue (VR). Hydrocracking reactions were carried out under the 430 °C and H2 pressure of 80 bar in an 100 mL high pressure reactor. New Molybdenum precursors were tested and their activities were compared with Mo-octoate. The Molybdeum-Phosphine precursor showed the best performances, high yield and low coke contents (below 0,5 wt%), in of hydrocracking for VR. To characterize the physicochem. properties of Moprecursor catalyst, various characterization techniques (NMR, XPS) were carried out. We confirmed that cokes in the reactor were contained the P atoms derived from ligand of Mo-precursor after hydrocracking of VR.
There are many compounds similar to this compound(1663-45-2)HPLC of Formula: 1663-45-2. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
