    Abstract: &bgr;-isophorone is formed by isomerizing &agr;-isophorone in the presence of an isomerizing catalyst (an aliphatic C5-20 polycarboxylic acid) in an isomerizing-reaction unit 1. The &bgr;-isophorone thus formed is oxidized with oxygen in an inert solvent in the presence of an oxidizing catalyst (a complex salt of a transition metal and an N,N′-disalicylidenediamine) in an oxidizing-reaction unit 2, thereby forming ketoisophorone. After removing a low-boiling point component, which is an impurity (non-conjugated cyclic ketone), from the reaction mixture using a distilling unit 3, a high-boiling component (oxidizing catalyst) is separated in a distilling unit 4, and then ketoisophorone is separated from the solvent in the separation unit 5. Thereafter, the solvent containing 0 to 5,000 ppm (weight basis) of the impurities and substantially free from ketoisophorone is recycled to the oxidizing reaction through a recycling line 6. According to the present invention, the combination of the isomerizing reaction and the oxidizing reaction makes it possible to produce ketoisophorone from &agr;-isophorone while maintaining the activity of the oxydizing catalyst.

    Abstract: In the presence of a catalytic system, an alcohol having “n” carbon atom(s) or a derivative thereof is allowed to react with carbon monoxide in a reactor 3 continuously, a higher bp catalyst component is separated from the resultant reaction mixture by a catalyst-separating column 5 to give a crude mixture, the crude mixture is fed to a higher bp component-separation column 8 to separate an overhead fraction from a bottom fraction containing at least a carboxylic acid having “n+2” carbon atoms, the overhead fraction is fed to a carboxylic acid-separating column 11, and are distilled in the presence of at least water and an ester of the carboxylic acid with the alcohol to separate a overhead fraction containing at least the ester and water from a bottom fraction containing the carboxylic acid having “n+1” carbon atoms. The overhead fraction from the carboxylic acid-separating column is fed to an aldehyde-separating column 14 to remove an overhead fraction containing an aldehyde. Such a process insures that impurities are efficiently separated from a reaction mixture by carbonylation of an alcohol, and that a carboxylic acid is purified easily at a lower cost.
