Low solubility of terephthalic acid in common solvents makes its industrial production very difficult and not environmentally benign. Ionic liquids are known for their extraordinary solvent properties, with capability to dissolve a wide variety of materials, from common solvents to cellulose, opening new possibilities to find more suitable solvents for terephthalic acid. This work presents studies on the solubility of terephthalic acid in ionic liquids, and demonstrates that terephthalic acid is soluble in ionic liquids, such as 1-ethyl-3-methylimidazolium diethylphosphate, 1-butyl-3-methylimidazolium acetate, and dialkylimidazolium chlorides up to four times higher than in DMSO. Addnl., the temperature effect and correlation of ionic liquid structure with solubility efficiency are discussed. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Synthetic Route of C4H7ClN2).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Synthetic Route of C4H7ClN2
