Abstract
This work presents the results of oxygen solubility in ionic liquids based on 1-alkyl-3-methylimidazolium cations. Solubility measurements have been carried out in gasometric apparatus at 22, 50 and 90 degrees C under atmospheric pressure. We report the Henry's constants. In general the occurrence of carbon-fluorine bonds and carbon-hydrogen bonds in ionic liquids (ILs) which can create hydrogen bonds with dissolved oxygen, significantly affects the growth of value of solubility constant K-H. Additionally, the stability of ILs towards molecular oxygen was tested. All ILs used in this study were stable in the presence of oxygen and free-radical initiator.
