n-nitrosoguanidine - Introduction
Nitrosoguanidine, the chemical formula is CH5N3O2, is an organic compound, with a certain degree of explosive. The following is a description of the nature, use, preparation and safety information of the Nitrosoguanidine:
Nature:
- Nitrosoguanidine are colorless crystals with a bitter taste.
-It is an unstable compound that can explode violently under high temperature or excited conditions.
- Nitrosoguanidine can be dissolved in water and alcohol solvents, and can also react with some organic compounds.
Use:
- Nitrosoguanidine is widely used as an explosive ingredient in the field of pyrotechnics and explosives.
-It can also be used as an intermediate for pesticides, such as insecticides and fungicides.
Preparation Method:
- Nitrosoguanidine is usually prepared by nitrating guanidine, that is, guanidine is dissolved in nitric acid and the substrate reaction is carried out at low temperature.
-The preparation process requires great care because the Nitrosoguanidine is explosive.
Safety Information:
- Nitrosoguanidine is a highly explosive compound and should strictly follow relevant safety procedures.
-Avoid excitation, vibration or high temperature conditions during operation.
-Avoid contact with combustibles, oxidants and acids to prevent chemical reactions.
-Keep dry and sealed during storage, away from fire and heat sources.
-Wear appropriate protective equipment such as safety glasses, gloves and protective clothing when operating the Nitrosoguanidine. Operate under well-ventilated conditions and avoid inhalation, swallowing or skin contact. In case of any doubt or unexpected situation, seek professional help immediately.
