HBR 48%

A clear, colorless to yellow liquid, HBR 48% is used as a source of bromine in industrial syntheses. A strong acid in an aqueous solution, HBR 48% is used for preparation of catalysts in PTA/PET production and as an electrolyte for energy storage. HBR 48% is available in a variety of concentrations.

Packaging: Hydrobromic acid is supplied in the following packaging:

  • Drums
  • Intermediate Bulk Containers – IBCs
  • Bulk Truck Loads

Flammability and Exclusivity: Hydrobromic acid is non-flammable and non-explosive. At high temperature it will release toxic fumes of hydrogen bromide.

Toxicity: LD50 (inhalation rate): HBr 100% 2,858 ppm/1h. Hydrobromic acid is corrosive to eyes, skin and mucous membranes. Actual inhalation may produce delayed pulmonary edema. Direct contact results in serious corneal and skin burns.

Storage & Handling: Keep containers tightly closed and protected from physical damage. Use fluorinated vinyl chloride resins or polyethylene glass-coated equipment. Avoid breathing vapors and any other bodily contact.

Store in a dry, cool, well-ventilated area, away from incompatible materials.
