1317-39-1, 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. Copper(I) oxide, cas is 1317-39-1,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
3-Chloro-4-nitro-benzonitrile Sodium nitrite (6.78 g in water (40 mL) at 0 C.) was slowly added to a solution of 4-amino-3-chloro-benzonitrile (10.5 g) in water (30 mL) and concentrated hydrochloric acid (30 mL) also at 0 C. After 10 minutes the solution was poured onto a suspension of cuprous oxide (3.48 g) and sodium nitrite (31.69 g) in water (100 mL) at 0 C. The ensuing mixture was stirred at 0 C. for 1 hour then at 23 C. for 1 hour. The resulting mixture was extracted with dichloromethane and the organic layer washed with saturated sodium chloride. The separated organic layer was dried over sodium sulfate and then concentrated to give 3-chloro-4-nitro-benzonitrile (11.31 g).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Copper(I) oxide, 1317-39-1
