  Efficient Synthesis of 1,3-Dialkylimidazolium-Based Ionic Liquids: The Modified Continuous Radziszewski Reaction in a Microreactor Setup

  摘要：

  By making use of a modified Radziszewski reaction, it is demonstrated that water-soluble 1,3-dialkylimidazolium-based ionic liquids can be produced in good yields (70-90%) and purities (>95%) starting from readily available, cost-effective monoalkyl-amines, glyoxal, formaldehyde, and mineral or organic acids. The homosubstituted 1,3-dialkylimidazolium salts feature high thermal stabilities similar to those of their heterosubstituted counterparts, and relatively low viscosities, thus fulfilling the requirements for solvent application. The effect of various parameters has been studied with the goal of improving yields for both the batchwise and continuous synthesis (making use of a microreactor setup), allowing for the production of a wide variety of ionic liquids and the introduction of functionalities. The applicability of these ionic liquids is demonstrated on the example of cellulose dissolution and the dehydration of fructose to 5-hydroxymethylfurfural.

  A composition for the immediate stopping of a free-radical polymerization comprises a) an inhibitor for the free-radical polymerization selected from among phenothiazines, b) an aprotic solvent and c) an ionic liquid. It serves to stabilize free-radically polymerizable monomers against free-radical polymerization. For the immediate stopping of free-radical polymerizations, the composition is added to a free-radically polymerizing system.
