Reaction Steps

A slurry of 11.6 g (0.1 mole) fumaric acid was dissolved in 30 ml water was mixed with 13 g of 30% aqueous solution of ammonium hydroxide (0.11 mol NH3). Carefully warming the slurry to boiling gave a clear solution. This solution was boiled to dryness over a period of 15 minutes to give a white crystalline solid. The solid was tumbled under nitrogen at 100 Torr, at 190°-200° C. for 4 hours to give a water insoluble, tan glasslike solid weighing 12.0 g. This solid was dissolved In 40 g of an aqueous solution containing 4.0 g of sodium hydroxide to form a pale yellow solution, pH 7.0, containing 25% solids.
