Vorschrift

Melaminium octamolybdate having a 2/1 molybdenum/melamine molar ratio was prepared in the following manner. 10 grams of melamine, 22.83 grams of molybdenum trioxide, 15.72 grams of ammonium sulfate and 300 milliliters of water were added to a 500 milliliter round-bottom flask equipped with a water-cooled condenser. The mixture was refluxed at about 105° C. for 2 hours while being stirred continuously and then was cooled to room temperature and filtered. A white crystalline solid was recovered from the liquid phase. The white product was washed with water and vacuum dried for 11/4 hours at 120° C. The white product was identified to be melaminium octamolybdate by infrared and x-ray diffraction analyses. 33.15 grams of the white solid product was recovered, representing a yield of 98.84 percent of the theoretical yield.
