A series of task-specific ionic liquids(TSILs) that bear an alkane sulfonic acid group were synthesized. Esterification of succinic acid with octanol was investigated using these TSILs as catalysts in both microwave irradiation and traditional heating ways. Effect of the anion and cation of the TSILs on catalytic performance was also investigated. Compared with elec. heating way, TSILs exhibited an enhanced reaction efficiency and short reaction time under microwave irradiation Effect of catalyst amount, reaction time and the acid-to-alc. ratio on conversion of succinic acid was systematically investigated. The results showed that the conversion of succinic acid reached 95.74% by using[PSPy]HSO4 as the catalyst under succinic acid/octanol molar ratio of 1:4, succinic acid mass fraction of 3wt% in TSILs, reaction temperature of 150°C, reaction time of 15 min and power of 400W. In addition, the [PSPy]HSO4 exhibited excellent stability and catalytic activity. It could be reused six times without considerable loss of activity and still had a conversion of 93.58%. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Computed Properties of C10H20N2O4S).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Computed Properties of C10H20N2O4S
