Diisopropyl oxide

The formula



Diisopropyl ether is secondary ether that is used as a solvent. It is a colorless liquid that is slightly soluble in water, but miscible with organic solvents. It is used as an extractant and an oxygenate gasoline additive. It is obtained industrially as a byproduct in the production of isopropanol by hydration of propene. Diisopropyl ether is sometimes represented by the abbreviation "DIPE".

1. Industrial Use:

Many types of industries use Di isopropyl ether. It is a component of many varnishes, paints and lacquers, for example. Chemical manufacturers also use it to synthesize and analyze chemicals. Both industrial and research chemists use Di isopropyl ether. The fuel industry uses Di isopropyl ether too. Di isopropyl ether is a cheaper alternative to ethyl and petroleum in fat extractions. It is also convenient and time-saving.

2. Solvent:

The most common use of Di isopropyl ether is as a solvent. Oil based substances dissolve in it, so it is the base of many waxes, dyes, paints and resins. It also removes oily substances like varnish. Ethers are usually good solvents because they are not very reactive. This means that substances dissolved in Di isopropyl ether are unlikely to change.

3. Use in Chromatography

Chemists often use Di isopropyl ether as a solvent in chromatography (a process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase). In liquid chromatography, the substance undergoing analysis travels through a liquid. Di isopropyl ether Di isopropyl ether is often the solvent through which the substance moves.
