The melting points of the ionic liquids vary with the different content of IM while they still keep satisfactory conductivity and viscosity. According to the analysis of its phase diagram, the eutectic point is about 16.5C with the mass percentage of IM 29%.展开更多

Electrochemical reduction of benzoylformic acid in room temperature ionic liquids as reaction media could be conducted with excellent performances without any additional supporting electrolyte. Electrolysis at glassy carbon electrode results in the formation of mandelic acid in 91% yield. And the electrochemical behavior of benzoylformic acid was investigated with the technique of cyclic voltammetry.展开更多

In combination with sol-gel method, titania, subsequently dye molecules (or polymer) were successfully fabricated onto the inner wall of SBA-15. Their structures were preliminarily characterized by FTIR and solid-state UV-Vis spectroscopy, thermal analysis, and BET surface area measurements, respectively.展开更多

The products can be isolated conveniently from the ionic liquid-catalyst system. The catalysts could be reused for more than 10 times still with satisfactory catalytic activity.展开更多
Reaction of ( S) α methylbenzylamine with Pd(OAc) 2 in anhydrous HOAc produced the chiral complex [Pd( μ O 2CMe)( S C 6H 4CHMeNH 2)] 2 (1).

The complex was characterized by 1H NMR spectroscopy, elemental analysis and a single crystal X ray analysis. The X ray crystal structure analysis revealed that complex 1 has four isomers: two outer and two inner isomers.展开更多
