The behaviour of a vanadium porphyrin complexes concentrate obtained from Darius crude oil has been studied on tic using a variety of solvent combinations and silica gel as the adsorbent. Reasonably good separation has been achieved with three solvent combinations in one dimensional run. Acetonitrile and acetonitrile, benzene, cyclohexane (3 : 5 : 11.3) afforded the best results in a double run.
