dicyanamide is a colorless to light yellow crystalline powder with the chemical formula CH4N4. It has the characteristics of high stability, low melting point, and easy to dissolve in water and organic solvents. The isoelectric point of dicyanamide is 6-7, which is slightly acidic.
dicyanamide has many uses in industry. It can be used as a pesticide (such as a herbicide) to inhibit the growth of plants by inhibiting the amine oxidase of plants. At the same time, dicyanamide can also be used in synthetic explosives, dyes, pharmaceutical intermediates and other fields.
There are many ways to make dicyanamide. Typically, it can be prepared by reacting ammonia gas with sodium cyanide (or potassium cyanide) under alkaline conditions. In addition, the simultaneous oxidation of ammonia and cyanide with hydrogen peroxide can also produce dicyanamide.
dicyanamide can cause eye and skin irritation, so you need to pay attention to personal protective measures during use and handling. At the same time, dicyanamide is more toxic, and ingestion or inhalation of dicyanamide may cause poisoning. Therefore, contact and inhalation of dicyanamide dust or vapor should be avoided, and the compound should be stored and handled properly to ensure safety. When using dicyanamide, you should follow safe operating procedures and consult professional advice.
