Txoj kev:
2-Bromo-3-pyridine formaldehyde tuaj yeem npaj tau los ntawm kev ua haujlwm 3-pyridine formaldehyde nrog hydrogen bromide. Hydrogen bromide yog thawj zaug dhau los ntawm lub raj mis ntxuav roj rau hauv cov tshuaj methanol ntawm 3-pyridine formaldehyde, thiab tom qab ntawd cov tshuaj tiv thaiv sib xyaw ua kom sov. Tom qab cov tshuaj tiv thaiv tiav, lub hom phiaj cov khoom tau txais los ntawm txoj kev xws li chav distillation lossis rho tawm.
Cov ntaub ntawv kev nyab xeeb:
2-Bromo-3-pyridine carboxaldehyde yog ib qho organic compound uas yuav tsum tau muaj kev ruaj ntseg tuav ntsuas thaum siv los yog tuav. Nws tuaj yeem ua rau khaus thiab ua rau tawv nqaij, qhov muag, thiab ua pa. Thaum siv, xyuas kom muaj cua zoo thiab hnav cov khoom tiv thaiv xws li hnab looj tes tiv thaiv, tsom iav, thiab qhov ncauj qhov ntswg. Tsis txhob nqus, noj, lossis tiv nrog daim tawv nqaij. Thaum khaws cia, nws yuav tsum khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab cov oxidants thiab khaws cia rau hauv qhov chaw txias, qhuav.
