Product Details of 14481-08-4. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), is researched, Molecular C22H38NiO4, CAS is 14481-08-4, about Molecular characterization of nickel and vanadium nonporphyrin compounds found in heavy crude petroleums and bitumens.
Electron impact mass spectroscopy (EIMS) anal. of the fractions of pyridine/water extracts of selected crude petroleums, separated by HPLC indicated V porphyrins in Cerro Negro and Wilmington moderate polar fractions and possibly in the Wilmington low polar fraction. The EIMS results provided no addnl. information on the metallo-nonporphyrins. Further purification of the highly polar fraction of the Wilmington crude petroleum extract showed the bonding for ≥1 type of Ni-containing nonporphyrin compound This Ni is bound as carboxylates. HPLC anal. of gilsonite (bitumen) indicated that the Ni is predominantly bound as metallopetroporphyrin, while a small portion eluted as a highly polar metallo-nonporphyrin fraction.
