253-52-1, 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. Phthalazine, cas is 253-52-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
A. A solution of phthalazine (2.5 g, 19.2 mmol) in concentrated sulfuric acid (30 mL) is treated slowly with potassium nitrate (2 g, 19.2 mmol). After 18 h the solution is cooled. Water (30 mL) is added. The solution is basified using 10 M NaOH to pH 13 (litmus). The solution is cooled for 18 h, filtered to give 5-nitro-phthalazine (0.93 g).
The chemical industry reduces the impact on the environment during synthesis,253-52-1,Phthalazine,I believe this compound will play a more active role in future production and life.
