| | Potassium chlorate Usage And Synthesis |
| Description | Potassium chlorate is an important compound that is widely used in various fields, including chemical industry, agriculture, medicine, etc. It is one of the first component used in the production of fireworks because of its explosive nature, where it serves as a oxidizer, which plays an important role in burning the firecracker at a fast rate. And the oxidizing property makes it an component of smoke composition to produce smoke grenades. It also shows a disinfectant effect, commonly used for preparing chlorine dioxide, a effective disinfectant that is often applied to water for eliminating bacteria, viruses, protozoa and odor-causing compounds. Besides, in the laboratory, potassium chlorate can be decomposed into oxygen, which is a far inexpensive source than a pressurized or cryogenic oxygen tank. Therefore, it can be used in medicine to treat pneumonia as well as gas poisoning, and employed as oxygen-supply system of aircraft, space stations, submarines, etc. Studies have proved that potassium chlorate is helpful in the cultivation of dormant tree, such as Longan trees to increase the yield of fruits when treated with potassium chlorate.

| | Description | Potassium chlorate, is a transparent, colorless crystal or white powder. It is soluble in boiling water and decomposes at approximately 750°F (398°C), giving off oxygen gas. Potassium chlorate is a strong oxidizer and forms explosive mixtures with combustible materials, such as sugar, sulfur, and others. Potassium chlorate is incompatible with sulfuric acid, other acids, and organic material. The four-digit UN identification number is 1485. Its primary uses are as an oxidizing agent in the manufacture of explosives and matches; in pyrotechnics; and as a source of oxygen. Sodium and potassium chlorates have similar properties. Chlorites are powerful oxidizing agents. They have one less oxygen than the base-state oxysalts. They form explosive mixtures with combustible materials, and in contact with strong acids, they can release explosive chlorine dioxide gas. | | Chemical Properties | Potassium chlorate is a white crystalline solid | | Chemical Properties | Potassium chlorate, KCI03, is transparent, colorless crystals or a white powder that is soluble in water,alcohol, and alkalies,and has a melting point of 356 °C.Used as an oxidizing agent,for explosives and matches, and in textile printing and paper manufacture. | | Uses | Potassium Chlorate is used in micro-smoke cold fireworks containing bright bead. | | Uses | Used (1) in matches, (2) in pyrotechnics, (3) as disinfectant, (4) as a source of oxygen upon heating. (Hazardous! Use of potassium perchlorate is recommended instead.) | | Uses | Explosives; fireworks; matches; printing and dyeing cotton and wool black; manufacture of aniline black and other dyes; source of oxygen; in chemical analyses. | | Uses | It is used for source of oxygen. | | Definition | potassium chlorate: A colourlesscrystalline compound, KClO3, whichis soluble in water and moderatelysoluble in ethanol; monoclinic; r.d.2.32; m.p. 356°C; decomposes above400°C giving off oxygen. The industrialroute to potassium chlorate involvesthe fractional crystallization ofa solution of potassium chloride andsodium chlorate but it may also beprepared by electrolysis of hot concentratedsolutions of potassiumchloride. It is a powerful oxidizingagent finding applications in weedkillersand disinfectants and, becauseof its ability to produce oxygen, it isused in explosives, pyrotechnics, andmatches. | | General Description | A colorless liquid. Denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Used to make other chemicals. Ignites organic materials upon contact . | | Air & Water Reactions | Soluble in water. | | Reactivity Profile | Metal chlorates are oxidants in the presence of strong acid; liberates explosive chlorine dioxide gas; liberates chlorine dioxide and carbon dioxide by heating a moist metal chlorate and a dibasic organic acid ; mixtures of perchlorates with sulfur or phosphorus are explosives [Bretherick 1979. p. 100]; mixtures of the chlorate with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979. p. 806]. A combination of finely divided aluminum with finely divided bromates (also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium, or zinc can explode by heat, percussion, and friction [Mellor 2:310 1946-47]. An explosion occurred during heating of a mixture of potassium chlorate and magnesium [Chem. Eng. News 14:451. 1936]. Gaseous ammonia, mixed with air reacts so vigorously with potassium chlorate that the reaction could become dangerous [Mellor 8:217. 1946-47]. A mixture of potassium chlorate and sodium amide explodes [Mellor 8:258. 1946-47]. If a drop of a solution of sulfur dioxide in ether or alcohol is added to powdered potassium chlorate, the mass explodes [Mellor 2:311. 1946-47]. Potassium chlorate and sulfuric acid react to cause fire and possible explosions [Mellor 2:315. 1946-47]. | | Hazard | Forms explosive mixture with combustible
materials (sulfur, sugar, etc.); strong oxidizing
agent. | | Health Hazard | Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. | | Flammability and Explosibility | Non flammable | | Industrial uses | Also known as chlorate of potash and potassiumoxymuriate, this is a white crystalline powder,or lustrous crystalline substance, of the compositionKClO3, employed in explosives, chieflyas a source of oxygen. It is also used as anoxidizing agent in the chemical industry, as acardiac stimulant in medicine, and in toothpaste.It melts at 357°C and decomposes at400°C with the rapid evolution of oxygen. It isodorless but has a slightly bitter saline taste.The specific gravity is 2.337. It is not hygroscopic,but is soluble in water. It imparts a violetcolor to the flame in pyrotechnic compositions. | | Safety Profile | Moderately toxic to
humans by an unspecified route. Moderately
