Introduction
CAS no: 16627-68-2 is the chemical identifier of 2,6-Dichloro-4-nitrophenol (DCNP), an organic compound with a wide range of applications in the chemical industry. DCNP is mainly used as an intermediate in the manufacture of agrochemicals, dyes, and pharmaceuticals. It is also used as a fungicide and herbicide, as well as a preservative for food and cosmetics. This paper will discuss the properties, production, and applications of DCNP.
Properties of 2,6-Dichloro-4-nitrophenol
DCNP is an off-white crystalline solid with a molecular weight of 221.04 g/mol. Its chemical structure is C6H3Cl2NO3, and it is soluble in water, ethanol, and ether. DCNP has a melting point of 90-91 °C, a boiling point of 256 °C, and a specific gravity of 1.8. It is relatively stable under normal storage and handling conditions, but it can be hydrolyzed in the presence of water or basic solutions.
Production of 2,6-Dichloro-4-nitrophenol
DCNP can be produced by the nitration of 2,6-dichlorophenol (DCP) with nitric acid. The reaction is typically carried out at a temperature of 10-20 °C and a pressure of 1-3 bar. The reaction mixture is then cooled, and the product is isolated by filtration. The crude product is then purified by recrystallization. The purity of the final product is typically greater than 99%.
