Introduction
M-nitroaniline is an organic compound. It is a yellow crystal with a peculiar foul odor.
The main use of m-nitroaniline is as a dye intermediate and as a raw material for explosives. It can prepare other compounds by reacting with certain compounds, such as nitrate compounds can be prepared by reacting with nitric acid, or dinitrobenzoxazole can be prepared by reacting with thionyl chloride.
The preparation method of m-nitroaniline can be obtained by the reaction of m-aminophenol with nitric acid. The specific step is to dissolve m-aminophenol in sulfuric acid containing nitric acid and stir the reaction, then cool and crystallize to finally obtain the product of m-nitroaniline.
Safety information: M-nitroaniline is a toxic substance that has an irritating effect on the eyes, skin, and respiratory tract. Contact with the skin can cause inflammation and redness, and inhalation of high concentrations of vapor or dust may cause poisoning. Wear protective glasses, gloves, protective clothing, and respirators when operating, and ensure that the operation is carried out in well-ventilated conditions. Any possible contact should be immediately rinsed with plenty of water and immediately treated with medical attention. Moreover, m-nitroaniline is explosive and should be kept away from open flames and high temperatures.
