Ionic liquids (ILs) are non-molecular solvents, which result from combinations of organic cations and various anions. ILs have many unique properties, including variable viscosity, high conductivity, high thermal stability, almost negligible vapor pressure, and a multitude of varying solvation interaction...
DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) is a strong tertiary amine base (pH 12.8) with a double heterocyclic structure, which has been widely used in organic synthesis. The twoNatoms in the molecule havesp2,sp3hybrid state, respectively. BothN1 (sp3) andN8(sp2) have a pair of lone...

There has been a large number of studies carried out to resolve the issue of instability posed by clay swelling. Over the past decades, numerous chemicals have been used as clay inhibitors, including inorganic salts, silicates, polymers, organic amines, ammonium compounds and so on. Recently, as...
Ionic liquids (ILs) have many outstanding advantages due to their unique structure and interaction, such as non-volatility, good thermal stability, reusability, and good extraction ability for various organic compounds and metal ions [19]. Electrostatic interaction is a common mechanism for the extrac...
