Syntheses of ionic-liquid salts of benzylmorpholines and their application as the extractants for the oil fractions refining from aromatic hydrocarbons
Ch.G. RasulovThere have been synthesized N-benzylmorpholines with the yield of 58.7-76.4 % via interaction of phenol, p-, m-crezols, p-(1-methylcyc-lohexyl)-phenol formaldehyde with morpholine and the ionic liquid salts have been obtained on the basis of them via quaternization reaction in the next stage. Physical-chemical properties, chemical structures and etc. of the synthesized n-, о-substituted phenol derivatives and ionic-liquids have been defined. It has been determined that synthesized ionic liquids have high electroconductivity in the range of 103-5.5.10-4 Sm. The ionic liquids synthesized on the basis of corresponding phenol compounds have been tested preliminarily as the extractants for the purification of kerosene fractions from aromatic hydrocarbons. The result of the analysis, carried out via IR-spectroscopy, showed that amount of aromatic hydrocarbons is reduced from 30 % to 10-12 % in the raffinate phases.
