Many Venezuelan crude oils have high concentrations of metals, especially vanadium and nickel, which are found predominantly as porphyrins. The authors report here the isolation of these organometallic compounds using either S.A.R.A. or vacuum sublimation methods, and their UV-visible and i.r. spectroscopic characterization.
