CYCLOHEXANONE (DNPH DERIVATIVE) - Introduction
Cyclohexanone 2,4-dinitrophenylhydrazone, chemical formula C12H10N4O4, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
Cyclohexanone 2,4-dinitrophenylhydrazone is a yellow crystalline solid with a distinctive odor. It is poorly soluble in water, but soluble in organic solvents such as ethanol and chlorinated hydrocarbons. It is a stable compound, but it decomposes when exposed to light or heat.
Use:
Cyclohexanone 2,4-dinitrophenylhydrazone is mainly used as one of the components of explosives and blasting supplies. Due to its explosiveness and high energy density, it is widely used in the military field and the preparation of high explosives.
Method:
The main preparation method of Cyclohexanone 2,4-dinitrophenylhydrazone is obtained by the reaction of phenylhydrazone and nitric acid under the catalysis of sulfuric acid. The specific preparation process requires laboratory conditions and corresponding operating techniques. It is necessary to pay attention to safety protection during the preparation process to avoid contact with fire sources, oxidants, etc.
Safety Information:
Cyclohexanone 2,4-dinitrophenylhydrazone is a highly explosive compound, so strict safety procedures need to be followed during use. It should be stored in a fireproof, explosion-proof container, and away from heat sources and open flames. Avoid mixing with oxidants, inflammables and flammable substances. Appropriate protective equipment such as goggles, gloves and protective clothing must be worn during handling and storage. At the same time, its waste and residues need to be accurately disposed of to prevent environmental pollution and possible safety issues. When handling this compound, strictly comply with relevant laws, regulations and guidelines.
