Meta nitro aniline (MNA) is an important intermediate chemical used in the manufacture of various industrial products. It is a yellow crystalline powder with a distinctive odor and a molecular formula of C6H6N2O2. MNA is a highly reactive compound that is used in a wide range of applications, from the production of dyes and pigments to the synthesis of pharmaceuticals.
This comprehensive guide provides an in-depth overview of MNA, covering its physical and chemical properties, applications, and safety considerations.

MNA is a versatile intermediate chemical used in a variety of applications, including:
MNA is primarily produced through the nitration of aniline. In this process, aniline is reacted with a mixture of nitric acid and sulfuric acid at controlled temperature and pressure. The reaction results in the formation of a mixture of para nitro aniline (PNA) and MNA. The MNA is then separated from the PNA through crystallization or distillation.
MNA is a hazardous chemical that poses potential risks to human health and the environment. It is classified as a toxic, corrosive, and flammable substance.
MNA should be stored in a cool, dry, and well-ventilated area. It should be kept away from incompatible materials, such as strong acids and bases, oxidizers, and reducing agents. MNA containers should be properly labeled and handled with care.
1. What is the difference between meta nitro aniline and para nitro aniline?
Meta nitro aniline and para nitro aniline are isomers with the same molecular formula but different structural arrangements. The nitro group (-NO2) is located at the meta position (1,3-position) in MNA and at the para position (1,4-position) in PNA.
2. Is meta nitro aniline soluble in water?
No, meta nitro aniline is insoluble in water but soluble in organic solvents such as ethanol, methanol, and benzene.
3. What are the toxicological effects of meta nitro aniline?
4. What are the environmental impacts of meta nitro aniline?
5. How can I safely dispose of meta nitro aniline?
MNA should be disposed of in accordance with local regulations. In general, it should be incinerated in a licensed hazardous waste incinerator.
6. What are the global market trends for meta nitro aniline?
The global MNA market is expected to experience steady growth in the coming years, driven by increasing demand from the dyes and pigments industry. Asia-Pacific is expected to be the largest regional market.
7. What are the major producers of meta nitro aniline?
8. What is the future outlook for meta nitro aniline?
MNA is expected to remain an important intermediate chemical in a variety of industries. With the increasing emphasis on sustainability, there is growing interest in developing more environmentally friendly processes for its production and use.
Meta nitro aniline is a highly reactive chemical that finds applications in a wide range of industries. Its physical and chemical properties make it suitable for use in the production of dyes, pigments, pharmaceuticals, and other products. Understanding the hazards associated with MNA and implementing proper safety measures is crucial for its safe handling and storage.
