摘要
报导了在乙醇-水体系中,分别用11-硅钨酸、12-硅钨酸与3,6-二(二甲氨基)-二苯并碘六环反应,制得一系列未见文献报导的大阳离子杂多酸盐。它们溶于N,N-二甲基甲酰胺、N,N-二甲基乙酰胺和二甲基亚矾等溶剂,但不溶于水、乙醇、甲醇、丙酮、氯仿和苯。还报导了它们的红外、紫外、热重分析,~1H-NMR及电导等性质。
A series of 3,6-di(dimethylamino)-dibenzopyriodonium salts of 11-tungstosilicate and 12-tungstosilicate were synthesized with K_(?)SiW_(11)O_(39), H_4SiW_(12)O_(40) and 3,6-di(dimethylamino)-dibenzopyriodonium formate in ethanol-aqueous solution respectively. They are insoluble in water, ethanol, methanol, acetone, chloroform and benzene, but soluble in DMA, DMF and DMSO. They were studied by IR spectra, thermogravimetric and differential thermal analyses, UV-spectra, molar conductance as well as ~1H-NMR spectra.
