With hydrazine hydrate and urea as raw materials, condensation may semicarbazide solution, and then with acetone synthesis, refining was finished. Hydrazine hydrate and urea will be mixed, heated to 97-104 °C , return to 6-7h. Down to 45 °C , filtration, may semicarbazide solution. The filtrate cooling to 25 °C , by adding acetone, the natural temperature 50-60 °C , heat 1h. Cooling to 20 °C below, filtration, cake drying, may acetonide ammonia urea. Ingredients weight ratio: hydrazine hydrate (40%): Urea: acetone = 1:0.67:0.56. Yield of 90%. As intermediates, the appearance is white powder, melting point 185-189 °C . Consumption of raw materials fixed: hydrazine hydrate (40%) 300kg / t, urea (industrial) 870kg / t, acetone (industrial) 720kg / t.
