Optimization of petroleum acid isolation from lower oil fractions of Vojvodina "Velebit" oil

Abstract

Petroleum acids can be obtained from oil and oil derivatives by alkaline extraction. The aim of this work was to optimize the process of alkaline extraction of petroleum acids from light commercial oil fractions of Vojvodina "Velebit" oil by changing the contact time of oil fraction with strong alkali and by changing the reaction temperature. Optimal conditions for isolation of petroleum acids have been determined to be 9 hours of contact time and reaction temperature of 90?C. Under these conditions the obtained petroleum acids yield was 88.38%. Identification of isolated acids was performed by GC-MS analysis.
