Experimental liquid–liquid equilibria of 1-methylimidazole with hydrocarbons and ethers

The liquid–liquid equilibria (LLE) of eight binary systems containing 1-methylimidazole and n-alkanes ( n-pentane, n-hexane), cyclohydrocarbons (cyclopentane, cyclohexane), aromatic hydrocarbons (hexylbenzene) or ethers (di- n-propyl ether, di- n-butyl ether, di- n-pentyl ether) have been measured f...

Description
Summary:The liquid–liquid equilibria (LLE) of eight binary systems containing 1-methylimidazole and n-alkanes ( n-pentane, n-hexane), cyclohydrocarbons (cyclopentane, cyclohexane), aromatic hydrocarbons (hexylbenzene) or ethers (di- n-propyl ether, di- n-butyl ether, di- n-pentyl ether) have been measured from 270 K to the boiling temperature of the solvent using a “cloud point” method. Experimental solubility results are compared with values calculated by means of the NRTL equation utilizing parameters derived from LLE results. Solubility of 1-methylimidazole in many other organic solvents (aromatic hydrocarbons, branch chain ethers and ketones) has been measured at temperatures higher than 293 K and no miscibility gap was observed. The interaction of 1-methylimidazole with different solvents is discussed.
