Hydrogen Bromide Supplier to Indianapolis Hydrogen Bromide (Br), a colorless, corrosive, irritating, toxic gas transported as a liquid in cylinders under its own vapor pressure, is one more cautiously useful PurityPlus® specialty gas available to Indianapolis customers from American Welding & Gas, Inc.. This gas is produced by the direct reaction of high-purity hydrogen with elemental bromine and the meticulously controlled reaction of sulfuric acid on certain brominated metals. Hydrogen Bromide traditionally has been associated with fumigation in agriculture. More discreet measures are used as a catalyst in pharmaceuticals. Earlier on, it was also widely used for the synthesis of HALON compounds used in fire-suppression systems. This is due to the fact that the resulting HALON compounds are high-density inert gases that can eliminate ground-level oxygen to put out a fire in a enclosed space with very little damage to property. HBr more recently has found use as a stratospheric ozone depleter and, that being the case, its use as a fumigant has been restricted to situations where total recovery looks to be achievable. HALON fire-suppression systems subject to existing chemical inventories as more environmentally sanctioned alternatives are introduced. Higher purities of Hydrogen Bromide are used by the electronics industry in certain unique plasma etching processes.
