The combustion kinetics of three bio jet fuel compounds farnesane, p-menthane and p-cymene, derived from natural terpenoids, have been investigated experimentally by an atmospheric high temperature flow reactor coupled with molecular beam mass spectrometric detection (MBMS). Quantitative speciation data for their oxidation chemistry in combustion is presented to provide an insight into the combustion behavior and provide detailed validation data for kinetic modeling. The experimental results are compared and discussed to analyze distinct combustion phenomena such as fuel consumption pathways and soot precursor chemistry. The fuel selection focuses on biotechnologically producible terpenoid components, namely the isoalkane 2,6,10-trimethyl dodecane (farnesane), the cycloalkane 1-isopropyl-4-methylcyclohexane (p-menthane) and the branched aromatic compound 1-isopropyl-4-methylbenzene (p-cymene). Literature data on farnesane (recently approved with up to 10% blending in Jet A-1) is limited and even scarcer for the two potential synthetic fuel additive species, p-menthane and p-cymene. The comprehensive, systematic experimental speciation data set including the single fuel components for lean to rich stoichiometries (0.5 to 1.5) is available in the supplemental material to this contribution.

Hydrophobic imidazolium-based ionic liquids (IL) act as catalysts for the epoxidation of unfunctionalized olefins in water using hydrogen peroxide as oxidant. Although the catalysts are insoluble in both the substrate and in water, surprisingly, they are very well soluble in aqueous H2 O2 solution, owing to perrhenate-H2 O2 interactions. Even more remarkably, the presence of the catalyst also boosts the solubility of substrate in water. This effect is crucially dependent on the cation design. Hence, the imidazolium perrhenates enable both the transfer of hydrophobic substrate into the aqueous phase, and serve as actual catalysts, which is unprecedented. At the end of the reaction and in absence of H2 O2 the IL catalyst forms a third phase next to the lipophilic product and water and can easily be recycled.

The perrhenate‐catalysed epoxidation of cyclooctene with aqueous H2O2 was performed in micellar media using imidazolium‐based ionic liquids (ILs) as surfactants. The catalytic performance of perrhenate was greatly increased in micellar media compared to IL used as neat solvent which allows for efficient use both of catalyst and IL. The choice of the surfactant alkyl chain length (C6 to C12) as well as the counterion (BF4−, TfO−, Cl−) is crucial for achieving high reaction rates. The positive effect of the addition of surfactants relies on formation of micelles. Best results are obtained for BF4− anion with long alkyl chain imidazolium cations, outperforming results for previously reported perrhenate ILs, while the use of Cl− anion leads only to similar reactivity. Cross‐over experiments revealed that the catalytically active micellar species forms in situ and that the BF4− anion promotes the reaction beyond a mere change in ionic strength. The use of Cl− anion as surfactant counterion bears potential as a novel approach for rapid screening of potentially catalytically active anions, which is exemplarily shown for tungstate anion.
