Procedure

The tungsten ester of glucoheptonic acid was prepared as follows: Approximately 330 grams (1 mol) of the sodium salt of tungstic acid (sodium tungstate) and 248 grams (1 mol) of sodium glucoheptonate were charged to an esterification vessel containing about 600 ml. of water as a solvent. With stirring, the temperature was maintained at about 25° C. for approximately 30 minutes. The mixture was thereafter diluted to a final volume of one liter with additional water.
