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. 1702-17-6, name is 3,6-Dichloropicolinic acid, the common compound, a new synthetic route is introduced below. HPLC of Formula: C6H3Cl2NO2
Under a nitrogen atmosphere, (Purity: 95.1 wt%) of 3,6-dichloropyridine-2-carboxylic acid, 63 g of toluene and 0.48 g of N, N-dimethylformamide was added dropwise at 80 C over 0.5 hour And 17.04 g of thionyl chloride was added thereto, followed by stirring at the same temperature for 1.5 hours. The reaction mixture was cooled to 50 C and concentrated under reduced pressure to give 47.67 g of a toluene solution of 3,6-dichloropyridine-2-carboxy chloride (confirmed by mixing the reaction mixture with methanol).
The synthetic route of 1702-17-6 has been constantly updated, and we look forward to future research findings.
