Pemasok yang Diaudit isopropyl alcohol An organic compound, the isomer of n-propanol, also known as dimethyl methanol, 2-propanol, and IPA in industry. It is a colorless, clear liquid with an odor like a mixture of ethanol and acetone. Soluble in water, also soluble in alcohol, ether, benzene, chloroform and other most organic solvents. Isopropyl alcohol is an important chemical product and raw material. Mainly used in pharmaceuticals, cosmetics, plastics, spices, coatings and so on.
Isopropyl alcohol, commonly known as fire wine, is a colorless flammable liquid with a strong odor at room temperature and pressure, molecular formula C3H8O. Isopropyl alcohol is the simplest secondary alcohol and is one of the isomers of propanol.
It has a smell similar to ethanol and acetone, slightly bitter and flammable. Miscible with water, ethanol, ether and chloroform, insoluble in salt solution. Can form azeotropic mixture with water (12.3% water content). Easy to produce peroxide. Low toxicity, median lethal dose (rat, oral) 2524mg/kg. High concentration of steam is narcotic and irritating
