Application of 872-49-1, The chemical industry reduces the impact on the environment during synthesis 872-49-1, name is 5-Chloro-1-methylimidazole, I believe this compound will play a more active role in future production and life.
Example 1 5-Chloro-1-methyl-4-imidazolesulfonic acid 33 g (0.28 mol) of 5-chloro-1-methylimidazole in 200 ml of fuming sulfuric acid are heated at 160-180 C. for 4 hours. After cooling, the reaction mixture is cautiously added to ice. The product crystallizes out from the cold aqueous solution (about 1.5 l). After recrystallizing twice from water, the title compound is obtained in the form of coarse yellowish crystals of melting point 309-310 C. Yield: 34 g (46.9% of theory).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Chloro-1-methylimidazole, other downstream synthetic routes, hurry up and to see.
