Storage method
Storage Precautions[13] Store in a cool, ventilated warehouse. The storage temperature does not exceed 30°C and the relative humidity does not exceed 80%. Keep away from fire and heat sources. The packaging is sealed. It should be stored separately from flammable (combustible) materials, reducing agents, etc., and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
Synthesis method
The preparation method is the reaction of dicyandiamide and ammonium nitrate. Dicyandiamide and ammonium nitrate are condensed at a ratio of 1:2 at 120 to 210°C. The reaction product is crystallized and sliced to obtain the finished product guanidine nitrate. Nitric acid can also be produced through the interaction of calcium cyanamide and nitric acid. guanidine.
Purpose
1. Mainly used for the preparation of nitroguanidine, which is the basic raw material and intermediate for dozens of drugs such as sulfamidine, trimethoprim, and pyrimethamine.
2. Used in the manufacture of explosives, disinfectants, photographic chemicals, etc. [14]
