Application of 16588-02-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 16588-02-6, name is 2-Chloro-5-nitrobenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 17 2-(3,4,5-Trichlorophenoxy)-5-nitrobenzonitrile In a 250 ml single-neck flask equipped with a magnetic stirrer and a reflux condenser fitted with a nitrogen bubbler were placed 8.68 g (0.0475 moles) of 2-chloro-5-nitrobenzonitrile 9.67 g (0.0489 moles) of 3,4,5-trichlorophenol, 6.75 g (0.0489 moles) of anhydrous K2 CO3, and 75 ml of acetonitrile. The mixture was heated to reflux and held there for 3 hrs. The reaction mixture was cooled to room temperature and diluted with 150 ml of water. The product separated as a solid. The solid was filtered off, washed thoroughly with water, and air-dried. The air-dried solid was recrystallized from a mixture of 200 ml of absolute ethanol and 100 ml of acetone to give 11.62 g (71% yield) of purified 2-(3,4,5-trichlorophenoxy)-5-nitrobenzonitrile as small white crystals, mp 162-164 C.
The synthetic route of 2-Chloro-5-nitrobenzonitrile has been constantly updated, and we look forward to future research findings.
