Description |
In the present study the extraction of benzene from mixtures of benzene and heptane is used as a model for the aromatic/aliphatic separation.
Liquid-liquid equilibrium data were collected for these mixtures at room temperature i.e 26 oC using room temperature ionic liquids such as 1--
butyl-3- methyl imidazolium hexafluorophosphate, N- Hexyl pyridinium bis ( trifluoromethyl sulphonyl) imide and 1- butyl- 2,3 - dimethyl –
imidazolium octyl sulfate. The selectivity for the benzene /heptane extraction, at T = 26 oC, increases from 15 to 55 with decreasing benzene
content in heptane, from 90 to 5 mol%. The distribution coefficient of benzene remained slightly above 0.2 over the entire concentration range.
These selectivities are about 2-3 times higher compared to conventional solvents, while the distribution coefficient for benzene is lower.
