Sources of common compounds: 3-Chloro-2-hydroxypyridine

The synthetic route of 13466-35-8 has been constantly updated, and we look forward to future research findings.

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. 13466-35-8, name is 3-Chloro-2-hydroxypyridine, the common compound, a new synthetic route is introduced below. name: 3-Chloro-2-hydroxypyridine

Chlorination: 40 g of 3-chloro-2-hydroxypyridine and 100 g of dichloroethane,DMF0.3g,Phosphorus oxychloride 56g was added to the reaction flask and refluxed.In the control,After the reaction is over,Distilled ethylene dichloride,Slowly add cold water to the reaction solution.After fully hydrolyzing, adjust the pH to 4-5 and steam it.Get 2,3-dichloropyridine,Dry at room temperature and dry at 43gThe purity is 99.1%.

The synthetic route of 13466-35-8 has been constantly updated, and we look forward to future research findings.
