It is an isomer of n-propanol, also known as dimethyl methanol and 2-propanol. It is also used as IPA in the industry. It is a colorless transparent liquid, flammable, and smells like a mixture of ethanol and acetone. It is soluble in water, but 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, paints, etc.
Colorless and transparent liquid, with an odor like a mixture of ethanol and acetone. It can be miscible with alcohol, ether, chloroform and water. It can dissolve a variety of organic and certain inorganic substances such as alkaloids, rubber, shellac, rosin, synthetic resin, etc. It forms an azeotrope with water and is insoluble in salt solution. It can be ignited and burned at room temperature, and the mixture of steam and air can easily form an explosive mixture.
The method is: take 0.5mL of isopropanol, add 1mL of 10% potassium iodide solution, 0.5mL of 1:5 dilute hydrochloric acid and a few drops of starch solution, shake for 1 minute, if it shows blue or blue-black, it means there is peroxide. It is similar to ethanol and propanol, but has the characteristics of a secondary alcohol.
As a chemical raw material, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl chloride, as well as fatty acid isopropyl ester and chlorinated fatty acid isopropyl ester Wait. In fine chemicals, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, medicines and pesticides, etc. It can also be used to produce diisopropyl acetone, isopropyl acetate and Thymol and gasoline additives.
It has a wide range of uses and can be freely mixed with water. It has a stronger solubility for lipophilic substances than ethanol. It can be used as a solvent for nitrocellulose, rubber, coatings, shellac, alkaloids, etc. It can be used to produce coatings, inks, extractants, aerosols, etc. It can also be used as antifreeze, cleaning agent, additive for blending gasoline, dispersant for pigment production, fixing agent for printing and dyeing industry, antifogging agent for glass and transparent plastics, etc. Used as a diluent for adhesives, antifreeze, dehydrating agent, etc.
As a standard for chromatographic analysis, it measures barium, calcium, copper, magnesium, nickel, potassium, sodium, strontium, nitrous acid, cobalt, etc.
Used as a defoaming agent for water-based fracturing fluids in oil wells. Air forms explosive mixtures, which can cause combustion and explosion when exposed to open flames and high heat, and can react strongly with oxidants.
In the electronics industry, it can be used as a cleaning and degreasing agent. In the oil industry, the extractant of cottonseed oil can also be used for degreasing animal-derived tissue membranes.
