Preparation of fructosazone (dextrosazone)

Preparation of fructosazone (dextrosazone)

2 ml of glacial acetic acid is mixed with 5 ml of water and 2 ml of phenylhydrazine and solution is shaken until a phenylhydrazine acetate is obtained. To this solution 1 g of fructose dissolved in 5 ml of water is added. The the reaction mixture is gently heated in a boiling water-bath. The yellow fructosazone usually begins to crystallize out after about 15 minutes’ heating. The heating is continued with occasional stirring for 30 minutes, and obtained solutions is filtered, wash with water and then with a few milliliters of methanol. Yield of fructosazone is about 1.8 g. The purification is performed by recrystallization from large amount of methanol or ethanol yielding bright yellow crystals.
