چکیده
The separation process between 5-hydroxymethylfurfural (HMF) and trace glucose in conversion is important the biphasic system (aqueous–organic phase), due to partial solubility property of HMF water. In addition, yield via dehydration reaction water low (under 50%) with use Brønsted acid as a catalyst. Therefore, this study was conducted optimize production products by using new hydrophobic ionic liquid (IL), which more selective than IL (1,3-dibutyl-2-(2-butoxyphenyl)-4,5-diphenyl imidazolium iodide) [DBDIm]I used solvent optimized for make HMF, levulinic (LA), formic (FA). showed high performance at 100 °C 120 min, 82.2% 14.9% LA, 2.9% FA presence sulfuric

Simulation and economic analysis of 5-hydroxymethylfurfural conversion to 2, 5-furandicarboxylic acid
Due to rising oil price and environmental aspects, research on alternatives for petroleum based chemicals and fuels is growing in recent years. Biomass is one potential raw material for producing non-petroleum derived chemicals and fuels. Different catalysts and reaction steps are required to generate the same products in comparison with the petroleum based processes. One possible starting mate...
متن کاملVery efficient conversion of glucose to 5-hydroxymethylfurfural in DBU-based ionic liquids with benzenesulfonate anion
Efficient conversion of glucose to 5-hydroxymethylfurfural (HMF), an important platform molecular for fuels and chemicals, is a promising topic in green chemistry. In this work, several new DBU-based (DBU = 1,8-diazabicyclo[5.4.0]undec-7-ene) ionic liquids (ILs) with benzene sulfonate (BS) anion were synthesized and used as the solvents for the dehydration of glucose to HMF. It was found that a...

Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...
متن کاملThe Highly Selective and Near-Quantitative Conversion of Glucose to 5-Hydroxymethylfurfural Using Ionic Liquids
A number of ionic liquids have been shown to be excellent solvents for lignocellulosic biomass processing, and some of these are particularly effective in the production of the versatile chemical building block 5-hydroxymethylfurfural (HMF). In this study, the production of HMF from the simple sugar glucose in ionic liquid media is discussed. Several aspects of the selective catalytic formation...

We here report experimental and kinetic modeling studies on the conversion of sucrose to levulinic acid (LA) and 5-hydroxymethylfurfural (HMF) in water using sulfuric acid as the catalyst. Both compounds are versatile building blocks for the synthesis of various biobased (bulk) chemicals. A total of 24 experiments were performed in a temperature window of 80-180 °C, a sulfuric acid concentratio...
