Procedure

Melaminium octamolybdate having a 2/1 molybdenum/melamine molar ratio was prepared by adding 5.00 grams of melamine, 11.42 grams of molybdenum trioxide, 28.57 grams of the sodium salt of benzenesulfonic acid and 300 milliliters of water to a 500 milliliter round-bottom flask equipped with a water-cooled condenser and refluxing the mixture at about 105° C. with continual stirring for 2 hours. The mixture then was cooled to room temperature and was filtered. A white crystalline product was recovered and was washed with water and vacuum dried at 100° C. for 11/2 hours. Infrared and x-ray diffraction analyses identified the recovered crystalline product to be melaminium octamolybdate. 15.83 grams of the product were recovered, representing a yield of 94.39 percent of the theoretical yield.
