Organophosphonotungstic HPA of Keggin Type with Sulfo, Taurine and Glycine Substituted Ethylphosphonic Acids as the Coordinate Center

College of Chemistry and Chemical Engineering, Southwest-China Normal University, Chongqing 400715

Received Date: 10 June 2002

The title compounds 2a-c were synthesized and characterized for the first time.Their proton numbers are around 3.2±0.15 and are not in proportion with the valid acidity-basicity of the central phosphonic acids.The entirety of phosphonic acids 1a-c is as the coordinate center of heteropoly anions of 2a-c.
