Diisopropyl ether water miscibility

Diisopropyl ether IJ08-20-3] is miscible with most organic solvents, but immiscible with ethylene glycol and glycerol. It is only slightly water soluble. Diisopropyl ether is an excellent solvent for natural oils, mineral oils, and waxes. It is used as an extracting agent and reaction medium in chemical and pharmaceutical syntheses. 

A characteristic of ACN is that it forms azeotropes with most organics that are not miscible with water and boil below ACN (Table 16.25). This means that it is difficult to recover the azeotropic entrainers once they have been used to remove water from ACN. This is not a problem if long-term drying of an ACN stream is involved and for this benzene, trichloroethylene and diisopropyl ether can be used.
