“…[5][6][7] Therefore, ILs have been widely used in catalytic processes, such as material synthesis, organic catalysis, and more recent biomass conversion. [8][9][10][11][12][13][14][15] In 2005, Ranu and Banerjee 16 first reported that the Michael addition process could be promoted efficiently in the presence of the basic IL [bmim]OH. More than 90% product yield was achieved for all active methylene compounds examined.…”

Ionic liquid (IL) catalyst attracts increasing attention during last few decades due to its excellent advantages of both homogeneous and heterogeneous catalyst. Here, a novel and efficient strategy for the production of trimethylolpropane (TMP) is proposed with basic IL catalysts. The catalytic activities of the IL catalysts are investigated. The effects of catalyst dosage, reaction temperature, time, and the molar ratio of the reactants are also studied. The results show that the basicity of the IL catalyst has a significant effect on the catalytic activity, where stronger basicity indicates higher catalytic activity. The IL 1-butyl-3-methyl imidazolium hydroxyl ([bmim]OH) is proven to be the most efficient catalyst where more than 84% isolated yield of TMP was obtained under optimized conditions. Furthermore, both the IL catalyst and butyraldehyde show excellent recyclability. Moreover, this IL catalytic system avoids the inevitable desalination encountered by current processes utilizing inorganic alkali catalysts.

Amorphous carbon-based sulfonated catalysts were generated from four kinds of biomass (lignin, cellulose, wood meal and D-xylose) by hydrothermal carbonization at various temperatures (225, 245 and 265 uC) followed by sulfonation, with a yield of 36-56%. All of these catalysts showed aromatic structure, hydroxyl and carboxyl groups, with a density of SO 3 H groups between 0.56 and 0.87 mmol g 21 . 5-Hydroxymethylfurfural (HMF) was produced from inulin in ionic liquids (ILs) in one step with the addition of carbon-based sulfonated catalysts, with a factual yield of 47-65% at 100 uC, 60 min. Moderate extension of reaction time (from 30 to 90 min) and increase of temperature (from 80 to 120 uC) promoted HMF production. Ethyl acetate was used as extractant, and about 39-55% of HMF can be recovered from ILs. One problem with these carbon-based sulfonated catalysts was that they would be partly deactivated in ILs for separate reuse, however, they can be easily regenerated by dilute sulfuric acid treatment. The carbon-based sulfonated catalysts exhibited good catalytic activity compared with traditional solid acid catalysts, and the carbon-based sulfonated catalyst/ILs reaction system showed high reusability. In consideration of the renewable as well as the high catalytic activity abilities, these biomass derived carbonbased sulfonated catalysts would be promising for industrial application.
