Potassium chlorate

Potassium chlorate is an inorganic chemical compound with the formula ClKO3 and CAS number 3811-04-9. This crystalline salt has a molecular weight of 122.55 g/mol and serves as a powerful oxidizing agent. It appears as white crystals or powder and is classified as a dangerous substance due to its oxidizing properties and acute toxicity. The compound is widely used in industrial applications requiring controlled oxidation reactions.

Potassium chlorate is a white crystalline solid that is odorless and highly soluble in water. It has a density of approximately 2.32 g/cm³ and melts at around 356°C. The compound is stable under normal conditions but decomposes when heated above 400°C, releasing oxygen gas. It demonstrates strong oxidizing properties and can react vigorously with organic materials, reducing agents, and combustible substances.

Potassium chlorate is primarily used as an oxidizing agent in various industrial applications including pyrotechnics, match manufacturing, and explosive compositions. It serves in the production of oxygen gas in laboratory settings and emergency oxygen generators. The compound is also utilized in textile bleaching, leather processing, and as a component in certain disinfectants and herbicides in controlled industrial environments.

Potassium chlorate requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas and avoid contact with combustible materials, organic substances, and reducing agents. Use non-sparking tools and equipment. Prevent dust formation and avoid friction or impact. Keep away from heat sources, open flames, and incompatible materials during handling operations.

Potassium chlorate must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed and separate from incompatible materials such as organic compounds, acids, metals, and reducing agents. Store in original containers on stable shelving away from high-traffic areas. Maintain temperatures below 25°C and ensure storage areas are equipped with appropriate fire suppression systems.

Potassium chlorate exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. In case of eye contact, flush with clean water for 15 minutes. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician after any significant exposure.

Potassium chlorate disposal must comply with local and national hazardous waste regulations as it is classified as dangerous waste. Contact licensed hazardous waste disposal companies for proper treatment. Never dispose of in regular trash, sewers, or waterways. Small quantities may be neutralized under controlled conditions by qualified personnel. Always consult local environmental authorities and follow applicable waste management protocols for oxidizing substances.

Potassium chlorate is classified under ADR Class 5.1 (Oxidizing substances) Packing Group II, requiring specialized transport procedures. It must be packaged in approved UN-specification containers with appropriate hazard labels and documentation. Transport vehicles must comply with ADR regulations including proper placarding, driver certification, and emergency equipment. Shipments require dangerous goods declarations and must follow prescribed routing restrictions.

Potassium chlorate is subject to multiple regulatory frameworks including CLP Regulation for classification and labeling, and REACH Regulation for registration and safety data requirements. It requires hazard communication through safety data sheets and appropriate labeling with GHS pictograms GHS03 and GHS06. The substance is not currently listed as an SVHC but may be subject to national restrictions regarding sale and use in certain applications.
