Characterization of the molecular composition of shale oil distillates and their sulfonated products by ultrahigh resolution mass spectrometry.

Among other applications, shale oil is used as a raw material for pharmaceutical products. The pharmaceutical effect of shale oil is attributed to its usually high sulfur content. To increase the sulfur content, shale oil is sulfonated with sulfuric acid and then neutralized with ammonia or sodium hydroxide. 
Both the untreated and treated shale oil exhibit high molecular complexity, although detailed characterization has not been possible to date. 
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) represents a modern analytical method characterized by high mass resolution. The combination with atmospheric pressure ionization methods such as atmospheric pressure photoionization (APPI) and electrospray ionization (ESI) thus represent a suitable method for the qualitative analysis of shale oils.
