Gas chromatographic identification of adamantanes in some Iraqi crude oils
Abstract
Adamantane was determined in three Iraqi crude oils using adductive crystallisation with thiourea and capillary gas chromatographic and infrared spectrophotometric methods. The amount of adamantane determined in these crude oils was 1–3 p.p.m. m/m. Certain derivatives of adamantane were also identified from their retention indices calculated from literature data.
