摘要

An unusual distribution on molecular composition of organic sulfur compounds (OSCs) was found in a crude oil from the Bohai Bay Basin (China) that contains negligible thiophenic sulfur compounds but abundant in C-30 and C-40 sulfides. The sulfides were separated from the crude oil by methylation/demethylation method and characterized by gas chromatography-mass spectrometry (GC-MS) and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). A novel series of C-30 OSCs that possess a bio-precursor of squalene were identified. The lexene (C-33) derived OSC was also identified for the first time in the crude oil, which indicates a strictly anaerobic condition during the early diagenesis of the source rock. Most C-40 sulfur compounds were verified to be sulfides having a beta-carotane skeleton. Most identified sulfides possess a thiolane group with a quaternary carbon atom or a thiane group within their carbon skeletons.
