Title:
ORGANIC SOLVENTS AS PYRIDINE AND IMIDAZOLIUM BASED IONIC LIQUID [Bmim]Cl AFFECTING FUNCTIONAL GROUPS AND PARAMAGNETIC PROPERTIES OF LOW RANK NALAIKH COAL
Financing:
This work has been done within the framework of the project (P2017-2375) sup- ported by the National University of Mongolia.

Annotation:
This work considers experimental results of low rank Nalaikh coal dissolution in organic solvents as pyridine and imidazolium based ionic liquid of [Bmim]Cl. The low rank coal and its treated samples were therefore analyzed by Fourier transformation infrared and electron paramagnetic resonance spectroscopy. Different paramagnetic centers are good resolved in the electron paramagnetic resonance electron paramagnetic resonance spectra of the extraction samples.
Keywords:
brown coal, pyridine, imidazolium based ionic liquid [Bmim] Cl, Fourier trans- formation infrared, electron paramagnetic resonance.
