20191-74-6 - Introduction
2-ethyl-5-nitroaniline, chemical formula C8H10N2O2, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
2-ethyl-5-nitroaniline is a yellow crystal, soluble in ether and acetone, slightly soluble in alcohol and water. It has a strong pungent smell. It is a strong oxidizing agent and can react strongly with reducing agents.
Use:
2-ethyl-5-nitroaniline is widely used in the synthesis of dyes and pigments, especially in the production of yellow and orange dyes. It can also be used as a raw material for explosive, gunpowder and explosive devices.
Method:
2-ethyl-5-nitroaniline can be prepared by ethylation of p-nitroaniline. A specific preparation method may be the reaction of nitroaniline with ethyl chloride under alkaline conditions. After completion of the reaction, pure 2-ethyl-5-nitroaniline can be obtained by crystallization and filtration.
Safety Information:
2-ethyl-5-nitroaniline is an irritating compound. It is irritating to the eyes, skin and respiratory tract. Therefore, appropriate protective equipment such as gloves, protective glasses and breathing masks should be worn during use. It should be kept away from combustibles and heat sources and stored in an airtight container. Avoid dust and gas during handling or use. If necessary, ventilation equipment should be used to ensure good ventilation. In case of accidental inhalation or skin contact, flush the affected area immediately with plenty of water and seek medical help if necessary.
