Sponge-like ionic liquids: a new platform for green biocatalytic chemical processes

Hydrophobic ILs based on cations with long alkyl side-chains are switchable ionic liquid/solid phases with temperature that behave as sponge-like systems (Sponge-Like Ionic Liquids, SLILs), being applied for producing pure liquid compounds (e.g. biodiesel, etc).

Critical Review

Fluorous ethers

Fluorous ethers, having one or more fluorous ponytails containing longer and shorter F(CxF2x)-perfluoroalkyl substituent(s) where x ≥ 6 or x = 1–5, respectively, were reviewed including some of their basic properties, synthesis and selected applications in chemical processes.

Direct transformation of carbohydrates to the biofuel 5-ethoxymethylfurfural by solid acid catalysts

Biomass-based mono-, di- and polysaccharides are directly converted to the biofuel 5-ethoxymethylfurfural (EMF) in ethanol by solid acid zeolite catalysts or by a combined zeolite–Amberlyst catalyst system in a one-pot, two-step process.
