Application of 288-36-8, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
In the reactor,Add 90% acetone (volume fraction) 400mL,Stirring,26.2 g of compound (01)Then 34.5 g of potassium carbonate powder was added,0.38 g copper iodide (CuI),1,2,3-triazole.External temperature was raised to 70 ,During the heating process, a large amount of gas is generated,The reaction was stirred at reflux for 5 hours.The reaction mixture was then distilled under reduced pressure at 40 C,When the reaction system is more viscous, add 45mL of water and continue to reduce the steam to distillate without acetone (no acetone in the gas phase). Distilled residue was added 300mL of water, 25% sulfuric acid was added dropwise at room temperature to adjust the pH to 1-2, a yellow suspension.Stir for 30 minutes, filter, and the solids are washed three times with water, 60 mL each. The resulting solid was dried to dryness at 70 C in vacuo,Have pale green solid 19.48g,Compound (1), purity 95.06%.
We very much hope you enjoy reading the articles and that you will join us to present your own research about 288-36-8, Happy reading!
