1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Application of 478935-29-4

A series of Bronsted acidic ionic liquids based on N-methylimidazole cation [C6mim] with different alkyl chain lengths and counter anions (HSO4–, H2PO4–, CH3COO–) were synthesized. The structure and acidity of these ionic liquids were characterized, and the catalytic activities under different reaction conditions were investigated. The ionic liquid with HSO4– anion and alkyl chain length of C6 attached to the cation exhibits the highest catalytic activity for bisphenol F (BPF) synthesis. Under the reaction conditions of temperature 90°C, reaction time 60 min, phenol/formaldehyde molar ratio 6:1 and catalyst/formaldehyde molar ratio 1:1, [C6mim][HSO4] shows excellent reaction activity with 80.5% yield and over 90% selectivity for bisphenol F synthesis. The ionic liquid was also found to have good reusability and low corrosion effects. These results suggest that the acidic ionic liquid [C6mim][HSO4] is a potential green approach to produce BPF. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Application of 478935-29-4).
