Technology Process of Bromous acid

There total 8 articles about Bromous acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

hydrogen bromide (10035-10-6,12258-64-9) + oxygen (80937-33-3) → bromohydroperoxide (75348-00-4) + bromine superoxide (67177-47-3,187886-97-1) + bromous acid (37691-27-3) + hypobromous acid (15656-19-6,13517-11-8) + hydroperoxyl radical (7782-44-7)

Guidance literature:

In gaseous matrix; byproducts: O3, OBrO; Irradiation (UV/VIS); mixt. of HBr/O2/excess Ne was introduced into vac. chamber and depositedon CsI plate cooled to about 6 K; irradiated by two xenon lamps (155-19 5 nm) for 240 min or at 350-385 nm for 180 min; not isolated; monitored by IR spectroscopy;

DOI:10.1016/j.cplett.2010.09.039

Reference yield:

malonic acid (141-82-2) + bromic acid (7789-31-3) → formaldehyd (50-00-0,30525-89-4,61233-19-0) + bromous acid (37691-27-3) + carbon dioxide (124-38-9,18923-20-1) + water (7732-18-5)

Guidance literature:

ruthenium(III)chloride; In acetic acid; mixing of solns. (BrO3(1-) 0.5 - 2.0*10**(-3) M, substrate 3.0 - 30.0*10**(-3) M), 60 - 80°C; reaction followed by analytical determination of bromate; Kinetics;

Reference yield:
