Separation of the chemical components of the oil residues in the Kirkuk oil wells and studying them spectrally

The aim of this study is characterize and determine the weighing ratio of chemical components in the oil residues in the kirkuk oil wells by separating each component alone then studying them spectrally to know the types of oils in this area and getting chemical information for other studies . this study has been completed according to the separating way of the chromatographic column by using organic solvents like n- hexane, toluene and which separate resin, aromatics and paraffin compounds. the isolation of the inorganic materials happens by using (ccl4) and distillation the isolated parts and studying them spectrally by x ray and determine the active groups.
