Design and synthesis of Brønsted-Lewis acidic tetraimidazolyl ionic liquids for efficient catalytic conversion of glucose to 5-hydroxymethylfurfural in water/1-octanol
A series of Brønsted-Lewis acidic tetraimidazolyl ionicliquids ([TeimILs]) were designed and synthesized by introducing Brønsted acid (-SO3H) in the cation and Lewis acid (AlCl3) in the anion. Among them, [Teim-PS][AlCl4]4 exhibited good catalytic performance in the conversion of glucose to 5-HMF in the biphasic system of H2O: 1-octanol= 1:2, and the conversion of glucose and the yield of 5-HMF can
