Procedure

Melamine molybdate was prepared in the presence of acetic acid as follows. 10 grams of melamine, 9.52 grams of acetic acid, and 250 ml water were dissolved together by refluxing in a 500 ml round-bottomed flask equipped with a stirrer and water-cooled condenser. 26.95 grams of ammonium dimolybdate was dissolved in 50 ml. hot water and then added to the first solution. A white precipitate formed immediately.
