Ferrous bromide txoj kev:
Nyob rau hauv ib tug reactor uas muaj dej, cov ntawv filings) yog ntxiv thiab bromine ntxiv rau hauv batches nrog nplawm. Cov tshuaj tiv thaiv yog nqa tawm ntawm 40 degree c los ua cov bromide. Tom qab ntawd, calcium hydroxide tau ntxiv los kho tus nqi pH, ua kom sov kom npau npau, thiab txias thiab sib cais kom tshem tawm hydrous hydroxide. Qhov frectrate yog evaporated thiab txias rau 30 degree c thiab sab laug sawv ntsug. Tom qab decolorization, pom kev, thiab evaporation rau ib ncig ntawm 210 degree c, nws txias kom tau calcium bromium.
