2-chloro-6-methyl-4-nitroaniline - Introduction
It is an organic compound with the chemical formula C7H7ClN2O2.
Nature:
-Appearance: White crystalline solid
-Boiling point: 344-346 degrees Celsius
-Melting point: 126-128 degrees Celsius
-Density: 1.39g/cm³
Use:
is an important intermediate compound that can be used to synthesize other organic compounds.
Mainly used in the synthesis of organic dyes, especially for dyeing cellulose fibers such as cotton, flax, etc. It can be used for dyeing yarns, textiles, rubber, plastics, pigments, etc.
Preparation Method:
It can be obtained by the reaction of 2-chloro-6-methyl-4-nitrobenzene and ammonia. First, in the presence of aluminum chloride and other catalysts, 2-chloro-6-methyl-4-nitrobenzene and excess ammonia reaction to generate pyridine, and then crystallization purification to obtain simple substance.
Safety Information:
It is a flammable solid and may cause irritation to the eyes, skin and respiratory system. Avoid inhalation, contact with skin and eyes. In the process of operation and storage should pay attention to fire and explosion prevention measures. In the event of a fire, use carbon dioxide, foam or dry powder extinguishing agent to extinguish the fire. When stored, it should be kept away from oxidizing agents and acidic substances. Pay attention to personal protective measures when using, such as wearing protective glasses, gloves and protective clothing. If taken by mistake or inhaled in large quantities, seek medical attention immediately.
