Recyclable supported Br?nsted acidic ionic liquid catalysts with non-aromatic cations for the oligomerization of isobutene under mild conditions

Br?nsted acidic ionic liquids with different type of cations (pyridinium, morpholinium, pyrrolidinium, imidazolium), N-sulfoalkyl chain length and different anions (triflate, hydrogensulfate and tetrafluoroborate) were prepared and immobilised on silica by adsorption. The ionic liquids were characterised by NMR and IR. Surface properties and Br?nsted/Lewis acidity of the supported catalysts were also determined. Their catalytic activity and recyclability were compared in the oligomerisation of isobutene to obtain products that can be used as jet fuel blending components after hydrogenation. The results proved that imidazolium ionic liquids can be replaced by less toxic non-aromatic versions without any loss in their activity and stability. By the introduction of shorter sulfoalkyl chain into the cation, excellent results could be obtained even under milder conditions (lower temperature and shorter reaction time). Catalytic activity was shown to correlate to the Br?nsted acidity of the catalyst.

Method for preparing maleate by catalyzing maleic anhydride with ionic liquid

The invention discloses a method for preparing maleate by catalyzing maleic anhydride with ionic liquid. The preparation method is characterized by comprising the following steps: mixing ionic liquidwith maleic anhydride and fatty alcohol, carrying out heating to 80-140 DEG C, and performing a reaction for 0.5-4 h to obtain maleate, wherein the usage amount of the ionic liquid accounts for 0.1-10% by mol of the maleic anhydride, and a molar ratio of fatty alcohol to maleic anhydride is 2-12. A high-added-value chemical with the completely-esterified maleate as a main product is prepared in the invention. The method is simple in process, mild in conditions, friendly to environment and high in double esterification degree; and the ionic liquid is high in activity, not prone to inactivationand capable of being cyclically used.

A two-phase system for the clean and high yield synthesis of furylmethane derivatives over -SO3H functionalized ionic liquids

A new and effective unique two-phase reaction system is investigated for the high yield production of tri(furyl)methane from furfural and furan. This strategy includes the use of an acidic aqueous phase (water + -SO3H functionalized IL) and furan phase, which significantly suppresses polymer formation, thereby increasing the yield of tri(furyl)methane. Furan serves as a reactant as well as an extraction solvent for the recovery of the condensation products. For comparison, different -SO3H functionalized ionic liquids are prepared and their performances evaluated for the condensation of furan and furfural. The ionic liquids with alkyl chain linkers are found to be more effective and acidic than those with imidazolium linked N-sulfonic acids. In addition, an increase in carbon chain length between imidazole/tri-ethylamine/pyridine and -SO3H, increases the catalytic activity of the respective ionic liquids. Among the several prepared ionic liquids, the strongly acidic imidazolium based butylsulfonic acid 6 shows the best activity with a maximum condensation product yield of 84%. This strategy offers a significantly high yield of the condensation products of furan and furfural compared to the traditional mineral acid route. The activity and stability of the -SO3H functionalized 6 is confirmed from seven successful recycles, in which there is no reduction in its activity. Finally, this new strategy is successfully extended for the condensation of furan derivatives (e.g. furan and 2-methylfuran) with several different aldehydes, ketones and alcohols.
