Descrizione

Descrizione generale

Diisopropyl ether is a colorless liquid. It is widely used as a solvent for the isolation of fats and oils. It can be synthesized from isopropyl alcohol. Its mixture with isooctane has been added to the gasoline fuel as an antiknocking agent.[1] Its synthesis from propylene and water in a single-pass trickle-bed reactor in the presence of an ion-exchange resin catalyst Amberlyst 15 has been proposed.[2] Its efficacy as a fuel additive has been reported. When released in the atmosphere, it undergoes photodecomposition by reacting with OH radicals. Kinetics and mechanism of its reaction in atmosphere have been reported.[3]

Applicazioni

Diisopropyl ether may be employed as a solvent for the preparation of aliphatic and aromatic cyanohydrins.[4]
