Use | diisopropyl ether is a good solvent for animal, vegetable and mineral oils, which can be used to extract nicotine from tobacco; it is also a good solvent for paraffin and resin. In industry, diisopropyl ether and other solvents are often used in the dewaxing process of paraffin-based oil. As a solvent is also used in pharmaceutical, smokeless powder, paint and paint cleaning, diisopropyl ether has high octane number and frost resistance, can be used as gasoline admixture. This product is easy to form peroxide, in the vibration to produce an explosion, often added to benzyl aminophenol as a stabilizer. The anesthetic effect of diisopropyl ether is lighter than that of ether, but the duration of anesthesia is longer. used as solvent, for the concentration and recovery of dilute solution of acetic acid or butyric acid, used as extraction solvent of sodium thiocyanate in wet acrylic fiber process used as chromatographic standard substance, solvent and extractant, also used in organic synthesis used as solvent, also used for concentrated recovery of acetic acid or butyric acid dilute solution |
production method | industrially, it can be recovered from the by-product of hydration of propylene sulfuric acid to isopropanol. Propylene reacts with sulfuric acid to form isopropyl hydrosulfate, which is then hydrolyzed to isopropyl alcohol. During the reaction, isopropyl hydrosulfate reacts with propylene to form diisopropyl sulfate, which reacts with isopropyl alcohol to form isopropyl hydrosulfate and diisopropyl ether. Diisopropyl ether was first obtained from the top of the column by distillation after the material after the sulfuric acid hydration reaction was steam stripped in the desorption column to release isopropyl alcohol and diisopropyl ether from the acid solution. In the laboratory, isopropyl ether can be obtained by dehydration of isopropyl alcohol with sulfuric acid or by hydrogenation of isopropyl alcohol with acetone. It can also be derived from the catalytic condensation of isopropanol with propylene. Diisopropyl ether can also be prepared by ion exchange resin method. |
