摘要: The effects of N-methylimidazole cation[Cnmim] with different alkyl chain lengths, the types of cations and anions of ionic liquids and the reaction parameters on the catalytic activity and the selectivity for 4,4'-bisphenol F were investigated. The hydrogen bonding between the hydroxyl of phenol and the C2-position hydrogen of imidazole moiety in hydrophilic imidazole-based ionic liquid has important influence on the selectivity for 4,4'-bisphenol F, and under the conditions of the molar ratio of phenol/[C4mim] [HSO4] 1:1, reaction temperature 65℃ and the theoretical molar ratio of phenol/formaldehyde 2:1, the selectivity for 4,4'-bisphenol F reached 69.1%. Compared with the high phenol/formaldehyde ratio reported in literatures, the low molar ratio of phenol/formaldehyde and the low reaction temperature can greatly reduce energy consumption, and has important significance for industrial application.
