- Аннотация: It was recently recognized that chemical and structural information about individual compounds of complex mixture can be revealed using isotope exchange combined with ultrahigh resolution mass spectrometry [1, 2]. This approach makes possible to enumerate active hydrogens and oxygens in thousands of compounds simultaneously. Here we present the application of the H/D exchange FT ICR MS for the investigation of humic substances, petroleum, bio-oil, wood pyrolysis produces etc. It was observed that compounds in regular crude oil have either 1 (naphthenic acids) or 0 (nitrogen containing compounds) labile hydrogen. Investigation of oil from ancient (V B.C.) Greek amphora revealed that ageing of oil in the presence of oxygen leads to the formation of compounds with 2 –OH groups. We have observed up to 3 labile hydrogens in wood pyrolysis products. We didn’t observe labile hydrogens in positive ions of nitrogen containing compounds of the bio-oil produced by hydrothermal liquefaction, such results indicates that such compounds are present in form of onium compounds. For humic substances, the number of labile hydrogens changes from 1 to 6 in the mass range 200-600 Da and increases with the molecular weight.
