| Abstract: | The effects of ratio, reaction temperature and time, velocity of temperature increasing on the production yield and quality have been studied. The experiment shows that an optimum condition is the molecular ratio of cyanamide to acid. Their ratio is (n (H 2NCN)∶n(H 2SO 4)=1∶0.5), the reaction temperature and time is 20～30℃ and 4 days respectively, the velocity of temperature increasing is 3℃/h. |
