  Preparation and Characterization of New Room Temperature Ionic Liquids

  摘要：

  A new series [CnOm mim] [X] of imidazolium cation-based room temperature ionic liquids (RTILs), with ether and alcohol functional groups on the alkyl side-chain has been prepared. Some physical properties of these RTILs were measured, namely solubility in common solvents, viscosity and density. The solubility of LiCl, HgCl2 and LaCl3 in room temperature ionic liquids was also determined. The features of the solid-liquid phase transition were analysed, namely the glass transition temperature and the heat capacity jump associated with the transition from the non-equilibrium glass to the metastable supercooled liquid. These properties compared with those reported for the 1-n-alkyl-3-methylimidazolium [C(n)mim][X] series. While the density and solid-liquid phase transition properties are similar for both series, the new RTILs present a considerably lower viscosity and an increased ability to dissolve HgCl2 and LaCl3 (up to 16 times higher).

  Disclosed is a process for producing ethylene glycol catalyzed by an ionic liquid, characterized in that the process includes the following three steps: (a) a carbonylation step of ethylene oxide and CO 2 catalyzed by an ionic liquid composite catalyst comprising a hydroxyl functionalized ionic liquid and an alkali metal salt under an aqueous condition to produce ethylene carbonate and ethylene glycol; (b) a hydrolysis step of reacting the reaction solution containing ethylene carbonate and the ionic liquid composite catalyst obtained in step (a) with water to produce ethylene glycol; (c) a purification step of dehydrating and refining ethylene glycol from the aqueous solution containing ethylene glycol and the catalyst produced in step (b). The present process has the following advantages: the catalyst has high activity, high suitability, and good stability, the reaction condition is wild, the conversion of ethylene oxide is high, the selectivity of ethylene glycol is high, and the process is simple.

  The present invention relates to fluidic devices for compartmentalizing samples. In particular, the devices and related systems and methods allow for compartmentalization by using one or more first chambers connect by a first channel (e.g., where the cross-sectional dimension of the first channel is less than the cross-sectional dimension of at least one first chamber).
