Also known as 2-propanol, commonly known as fire wine, it is a colorless, flammable liquid with a strong odor under normal temperature and pressure. The molecular formula is C3H8O. Isopropanol is the simplest secondary alcohol and one of the propanol isomers. Colorless transparent liquid with a odor like a mixture of ethanol and acetone. Soluble in water, also soluble in most organic solvents such as alcohol, ether, benzene, chloroform, etc. Isopropanol is an important chemical product and raw material. Mainly used in pharmaceuticals, cosmetics, plastics, fragrances, coatings, etc. Belongs to a medium explosion hazard. It is a flammable and low-toxic substance. The toxicity of vapor is twice that of ethanol, and the toxicity when taken orally is the opposite. Isopropyl alcohol can replace ethanol as a solvent in many cases. It is a good solvent and chemical raw material. It is used in coatings, medicine, pesticides, cosmetics and other industries. It is also used in the production of acetone, isopropyl ester, isopropylamine (atrazine). raw materials), diisopropyl ether, isopropyl acetate and thymol. It is the first chemical product obtained from petroleum raw materials in the history of petrochemical development.
