Abstract

563,164. Distilling ketones. SHELL DEVELOPMENT CO. April 22,' 1943, No. 6490. Convention date, May 30, 1942. [Class 32] Ketones are separated from mixtures thereof with water or an alcohol by subjecting the mixture to fractional distillation in presence of an added liquid polyhydric alcohol, polyhydric alcohol ether, or hydroxy alkylamine which increases the relative volatility of the ketone and is characterised by having a higher boiling point than the components of the mixture, and by being incapable of forming an azeotrope with or of reacting chemically with any of the components, the fractional distillation being performed so that a substantially alcohol and water free ketone is recovered as the overhead fraction while the alcohol and/or water and the added component are recovered as a bottom fraction. Specified added compounds, are ethylene, diethylene, propylene, butylene and like glycols, glycerols, carbitols, cellosolves, glycerol ethers ; mono-, di-, or triethanolamines, propanolamines, and butanolamines. Ketones specified comprise acetone, methyl ethyl ketone, diethyl, methyl n-propyl, methyl isopropyl, ethyl npropyl, ethyl iso propyl, methyl-n-butyl methyl isobutyl, methyl tert-butyl, methyl sec.-butyl ketones. Acetone containing 27-30 per cent water is fed through line 10 into dehydrating column 11 heated by coil 12, and the auxiliary liquid, e.g. ethylene glycol is supplied through line 15. Acetone containing only .2 per cent, water is withdrawn through line 16 to condenser 17 and thence through line 18, part being recycled as reflux through line 19. The liquid bottoms comprising water and ethylene glycol are passed through.line 22 to stripper 24 where anhydrous glycol is separated as a bottom product and recycled through line 30, the water and any acetone being recovered. overhead to condenser. 26. The process is particularly applicable to the recovery of anhydrous acetone from a mixture of acetone, isopropyl alcohol and water produced in the oxidation or dehydrogenation of isopropyl alcohol.
