  摘要：

  The salts, [Ph(2)B{OCH(2)CH(2)N(Me)(CH(2))(n)}(2)][Ph(4)B(3)O(3)](n = 4,5), were prepared in moderate yields in MeOH solution from reaction of Ph(2)BOBPh(2) with [N(CH(2))n(Me)(CH(2)CH(2)OH)][OH] and PhB(OH)(2) in a 1:2:4 ratio. The reactions also lead to Ph(3)B(3)O(3). Both salts were characterized by NMR ((1)H, (13)C, (11)B) IR, and single-crystal XRD studies. The salts are comprised of cationic monoborates (zwitterionic, 2N(+) and 1B(-)) and tetraphenylboroxinate anions. (C) 2009 Elsevier B.V. All rights reserved.

  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.
