Propylene is a colorless gas with a faint petroleum like odor. It is shipped as a liquefied gas under its own vapor pressure. For transportation it may be stenched. Contact with the liquid can cause frostbite. It is easily ignited. The vapors are heavier than air. Any leak can either be liquid or vapor. It can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used to make other chemicals. Can cause explosion.;GasVapor; GasVapor, Liquid; Liquid;GasVapor; Liquid;COLOURLESS COMPRESSED LIQUEFIED GAS.;Colorless gas with a faint petroleum like odor.

Potassium iodide is an inorganic compound with the chemical formula KI. This white salt is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with. Potassium iodide occurs naturally in kelp. Kelps iodide content can range from 89 μg/g to 8165μg/g.Aged and impure samples are yellow because of the slow oxidation of the salt to potassium carbonate and elemental iodine.Potassium iodide is medicinally used for thyroid blockade, thyroid storm and also as an expectorant. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system. Alternative Names: Potassium monoiodide. CAS No. 7681-11-0. Molecular formula: IK.
