実験手順

590 g (5 mols) of 4,5-dihydroxy-2-imidazolidinone and 300 g (5 mols) of urea were dissolved in 1 liter of water. 30 ml of concentrated hydrochloric acid was added to the solution and the mixture was stirred at 90° C. for 1 hour. After cooling, the crystals thus precipitated were collected by filtration, washed with water and dried to obtain 526 g (yield: 74%) of glycoluril. The melting point of glycoluril was above 300° C.
