Triazolium‐based Ionic Liquids Supported on Alumina as Catalysts to Produce 5‐HMF from Fructose

The dehydration of fructose to selectively produce 5‐HMF was catalytically developed in a new type of ionic liquids based on triazoles supported on alumina (Al2O3). The synthesis of triazoles by 1,3‐dipolar cycloaddition allows for creating a tailor‐made triazole, that was eventually used to design...

Description
Summary:The dehydration of fructose to selectively produce 5‐HMF was catalytically developed in a new type of ionic liquids based on triazoles supported on alumina (Al2O3). The synthesis of triazoles by 1,3‐dipolar cycloaddition allows for creating a tailor‐made triazole, that was eventually used to design catalysts based on triazolium‐based ionic liquids. In this work, four catalysts based on triazolium‐ionic liquids supported on Al2O3 were synthesized to produce 5‐HMF from fructose in DMSO as the reaction solvent. According to their molecular structure, the catalysts were tagged as TR1/Al2O3, TR1‐HSO4/Al2O3, TR2/Al2O3, and TR2‐HSO4/Al2O3. Ionic Liquids: Supported triazolium‐based ionic liquid catalysts are alternatives to dehydration of fructose in 5‐HMF obtaining conversion of around 100 %. Triazoles can be synthesized by 1,3‐dipolar cycloaddition and used as catalysts. This is the first example where triazolium‐based ILs are used in obtaining 5‐HMF in a particular way.
