Abstract
PURPOSE: To obtain a by-product diisobutyl ketone fraction of high quality which contains acidic impurities a little, by the alkali treatment of a residue after removal of a product from a reaction mixture through the distillation in the production of methyl isobutyl ketone.
CONSTITUTION: In the production of methyl isobutyl ketone from acetone and/or isopropanol by aldol condensation, hydrogenation, etc., alkali treatment is carried out when a by-product diisobutyl ketone fraction is isolated after removing a light fraction, such as methyl isobutyl ketone, etc. from a reaction product by distillation. The diisobutyl ketone fraction contains diisobutyl ketone as a principal component and small amounts of 4,6-dimethyl-2-heptanone, diisobutyl carbinol, etc. In the alkali treatment, 0.1W10wt.% aqueous solution of NaOH, etc. is preferably used. The aqueous solution is preferably used in an amount of 0.1W30 parts by volume per part by volume of the residue or diisobutyl ketone fraction to be treated
