RESUMEN
In this study, Molybdenum precursors were synthesized with Triphenylphosphine, 1,2-Bis(diphenylphosphino)ethane, Pyridine, 2,2-Bipyridine 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 physicochemical 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.
RESUMEN
In this study, Molybdenum precursors were synthesized with butanoic acid, hexanoic acid, nonanoic acid, decanoic acid, and undecanoic acid. In order to determine chemical structure of Synthesized molybdenum precursors, 1H(13C)-NMR, EA and ICP were used pyrolysis properties were measured TGA. The molybdenum precursors was used for Hydrocracking of Vacuum R1esidue (VR). It was shown that molybdenum nonanoate(3) was shown the lowerst Toluene Insoluble and Gas Product about 2.1 and 5.0 percent.
RESUMEN
In the title compound, C(22)H(28)O(3), the dihedral angle between the benzene rings is 3.47â (13)° and the five-membered furan ring is essentially planar with a largest deviation of 0.0052â (14)â Å. The Csp(2)-Csp(2) bond length between the two benzene rings [1.443â (3)â Å] is considerably shorter than those between the benzene and tertiary C atoms [1.538â (3) and 1.530â (3)â Å], which are sp(2)-sp(3) hybridized. C-Hâ¯π inter-actions involving the furan and benzene rings are found in the crystal structure.
