Methyl Ethyl Ketone and Water - Big Chemical Encyclopedia

One used methyl ethyl ketone and water as the azeo-troping agent (81) the other employed methanol (1). [Pg.207] An even more advantageous condition exists in the case of the toluene range hydrocarbons when methyl ethyl ketone and water are added. A ternary azeotrope of methyl ethyl ketone-water -nonaromatic hydrocarbons distills below 176° F.

Methyl ethyl ketone, solvent - Big Chemical Encyclopedia

The MEK process ( methyl ethyl ketone — toluene solvent) is widely used. Wax crystals are formed by chilling through the walls of scraped surface chillers, and wax is separated from the resultant wax—oil—solvent slurry by using fliUy enclosed rotary vacuum filters. [Pg.211]
