摘要
The isolation and characterization of vanadium porphyrins in Tahe crude oil has been carried out. The vanadium porphyrins were at first isolated by methanol extraction and then purified by column chromatography and thin layer chromatography. Ultraviolet-visible spectrophotometry and laser desorption ionization-time of flight mass spectrometry were employed to characterize the vanadium porphyrins. The vanadium porphyrins in Tahe crude oil are chiefly ETIO homologues(C 26～C 39) with a small amount of DPEP homologues (C 29～C 39) and RHODO-ETIO homologues(C 29～C 39).
