Diisopropyl ether ( DIPE ), often also referred to as isopropyl ether (IPE), is a colorless liquid. It is an excellent solvent for animal, vegetable and mineral oils, fats, waxes and some natural resins.

Properties and Uses

IPE is generally not used as a solvent for synthetic resins, although it dissolves, cellulose nitrate and ethyl cellulose in the presence of low molecular weight alcohols. IPE tends - as well as many other ethers - to form peroxides, which are formed during the IPE even on prolonged standing in the dark. To prevent this, is added (a mixture of antioxidants) hydroquinone or IONOL.

Safety characteristics

Diisopropyl ether readily forms flammable vapor - air mixtures. The compound has a flash point of -28 ° C. The explosion range is between 1.0 vol % ( 45 g/m3) as the lower explosive limit ( LEL) and 21 vol % (900 g/m3 ) and upper explosive limit (UEL ). The maximum explosion pressure is 9.3 bar. The marginal gap width was determined to be 0.94 mm (50 ° C). The result is thus a mapping in the explosion group IIA. The ignition temperature is 405 ° C. The fabric falls within the temperature class T2.

Use

Diisopropyl ether is used as the extraction agent in the pharmaceutical and chemical industries. It is used as a substitute for diethyl ether, when a solvent is desired, less volatile

Safety

IPE affects low acute toxicity similar to diethyl ether anesthetic on humans and animals, but also shows almost the same negative effects such as muscle contractions, spasms, nausea and a pronounced excitation phase.

Isomerism

Di -n- propyl ether is structural isomer of diisopropyl ether ( di-i -propyl ether ).
