Oxygen-containing organic compounds of the bituminous components of high-moor peat from the south of Western Siberia

The composition of the bituminous components of high-moor peats from the south of West Siberia (Tomsk oblast, Temnoe bog) was analyzed. The similarity of the compositions of fatty acids, n-alkan-2-ones, n-aldehydes, tetra- and pentacyclic ketones, esters, and aromatic alcohols in all of the test peat samples was found. At the same time, the total concentration of alkanones, which prevailed among the oxygen-containing organic compounds in raised bog peats, was small in floating bog peats. The peats of the floating bog section were differed from the raised bog peats in the composition of pentacyclic alcohols, which included compounds from the lupene group in addition to oleanene derivatives. Tetracyclic alcohols in floating bog peats mainly consisted of saturated structures, whereas raised bog peats contained exclusively unsaturated stenols. The differences in the concentrations and composition of fatty acids, acyclic ketones, aldehydes, esters, steroids, and terpenoids observed in peats from two sections of the Temnoe bog mainly depend on the conditions of peat buildup and burial.
