Abstract
Bitumen extraction is a promising project of brown coal processing. It raises the task of identifying and quantifying the components of recoverable bitumen. In this paper, the method of gas chromatography-mass spectrometry is used to solve this problem. The composition of high-molecular fatty acids of brown coal bitumen from the Tyulgan deposit was studied taking into account the patterns of molecular ion fragmentation for the butyl esters of fatty carboxylic acids under ionization by electron impact. The ethanol extract fraction was investigated. The NIST-11 Database and ChemStation D.01.02. software was used to identify the butyl esters of fatty carboxylic acids.
