Basic Information
Product Name: Potassium Bromate
Chemical Formula: KBrO3
Molar Mass: 167.00 g/mol
CAS Number: 7758-01-2
Appearance: Colorless crystals or white powder
Solubility: Soluble in water (≈3.5 g/100 mL at 20°C), slightly soluble in ethanol, insoluble in acetone
Primary Uses
Food Industry (Historical Use, Now Restricted):
Flour Improver:
Previously added to bread and pastry dough to strengthen gluten via oxidation, improving dough ductility and baking quality.
Ban Reason: Classified as a Group 2B possible human carcinogen by IARC, linked to potential kidney, thyroid damage, and gastrointestinal cancer with long-term intake.
Current Status: Banned in most countries (e.g., China, EU, US), with only limited exceptions (e.g., Japan allows ≤3 mg/kg residue in flour).
Industrial and Laboratory Applications:
Analytical Chemistry:
Used as a primary standard for determining elements like arsenic, antimony, and bismuth, or for standardizing sodium thiosulfate solutions (bromate method).
Pharmaceutical Synthesis:
Used in preparing bromine-containing drug intermediates (requires strict safety protocols).
Wool Processing:
Historically used as an oxidant in wool dyeing, now gradually replaced by safer reagents.
Safety and Hazards
Toxicity and Health Risks:
Acute Poisoning: Ingestion may cause nausea, vomiting, abdominal pain, and diarrhea, potentially leading to renal failure, neurological damage, or death (adult lethal dose ≈10 g).
Chronic Toxicity: Long-term exposure may induce cancer (e.g., thyroid and kidney tumors in animal studies) and irritate skin/mucous membranes.
Safety Precautions:
Personal Protection: Wear nitrile gloves, safety goggles, and protective clothing; avoid inhalation of dust or skin/eye contact.
Storage and Transportation:
Store in a cool, dry, sealed container away from fire, heat, reducing agents, and organic materials (e.g., sulfur, phosphorus, charcoal).
Classified as an oxidizing substance during transport; keep separate from food and pharmaceuticals.
Emergency Response:
Spillage: Cover with dry sand, avoid dust, and collect for safe disposal (e.g., convert to potassium bromide using a reducing agent).
Ingestion: Induce vomiting immediately and seek medical help; gastric lavage with sodium sulfate (avoid sodium chloride solutions, which may form sodium bromide and exacerbate toxicity).
Environmental Impact
Ecotoxicity: Soluble in water, posing risks to groundwater/surface water and aquatic life (e.g., fish, algae). Avoid untreated wastewater discharge.
Degradation: Slowly reduced to bromide ions via photolysis or microbial action in the environment, but residual effects may disrupt ecological balance.
Summary
Potassium bromate's use in food has been widely banned due to its oxidizing power and carcinogenic potential, with applications now limited to specialized industrial/laboratory settings under strict safety guidelines. The trend favors low-toxicity, eco-friendly alternatives. Always consult updated regulations and implement full protective measures when handling this chemical to prevent harm to humans and the environment.
