TL;DR: The heterogeneous acid-promoter process is a potent alternative to corrosive homogeneous acids for lignocellulose fractionation in integrated biorefineries.

TL;DR: In this article, an oxidizing air-acetylene flame is used to determine tellurium in the 0.1-20 ppm range, and a carbon-rod atomizer is used after the MIBK extract has been washed with 0.5 M hydrobromic acid to remove the residual iron.

TL;DR: In this article, the main physico-chemical features, as well as gasoline blending features of eight diol derivatives (1,3-diisopropyl and 1, 3-di-tert-butyl glycerol ethers) have been estimated in order to reveal the relations between the molecular structures of the compounds and their efficiency as the gasoline oxygenated additives.

TL;DR: Calcium D-glucarate was converted into D- glucaro-1,4:6,3-dilactone on 32-g, 1-kg, and 22-kg scale, using azeotropic distillation with methyl isobutyl ketone to drive the dehydration.
Abstract: Calcium d-glucarate was converted into d-glucaro-1,4:6,3-dilactone on 32-g, 1-kg, and 22-kg scale, using azeotropic distillation with methyl isobutyl ketone to drive the dehydration. The crystalline product was ≥99.5% pure by GC and NMR, and overall yield was as high as 72%.

TL;DR: In this paper, a biphasic system that consists of 1-butyl-3methylimidazolium chloride ([BMIM]Cl) as the ionic liquid phase and methyl isobutyl ketone (MIBK), as the extractant phase, was identified as the dominant force that suppresses the extraction efficiency of 5-hydroxymethhylfurfural (5-HMF) from ionic liquids.
Abstract: Ionic liquids have been widely studied as effective reaction media for the conversion of glucose or cellulose to 5-hydroxymethhylfurfural (5-HMF). However, the recovery of 5-HMF from ionic liquids, typically carried out by extraction, has been encountered with very low extraction efficiency, which limited the reusability of the solvents. Through this work, based on the model biphasic system that consists of 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) as the ionic liquid phase and methyl isobutyl ketone (MIBK) as the extractant phase, the dominant force that suppresses the extraction efficiency of 5-HMF was identified as being the strong hydrogen bonding between 5-HMF and [BMIM]Cl. Solvent mediation with functional promoters have been established as a new strategy to shift this force, resulting in improved extraction efficiency of 5-HMF from the ionic liquid. For example, with ethanol as a promoter, the distribution coefficient of 5-HMF was about 10 times higher than that without a promoter.
