Abstract: PURPOSE:To obtain 2-chloropropionic acid in high concentration and selectivity by oxidizing 2-chloropropionaldehyde with oxygen or an oxygen-containing gas in liquid phase in the presence of an iron compound, a cobalt compound and a molybdenum compound. CONSTITUTION:The objective 2-chloropropionic acid can be produced by oxidizing 2-chloropropionaldehyde with oxygen or an oxygen-containing gas in liquid phase (especially at 40-90 deg.C) using a catalyst comprising an iron compound (e.g. ferric salt of 2-chloropropionic acid), a cobalt compound [e.g. cobalt(II) acetate] and a molybdenum compound (e.g. molybdenum naphthenate). The process enables the industrial production of 2-chloropropionic acid in a low- corrosion environment in high selectivity. 2-Chloropropionic acid having increased concentration can be produced by the process. The process is advantageous because the obtained 2-chloropropionic acid does not contain detectable amount of 2,2-dichloropropionic acid.

Abstract: PURPOSE:To prevent deterioration in catalyst activity, by treating a liquid phase containing a catalyst with active carbon and reusing the catalyst in oxidizing 2-chloropropionaldehyde with an oxygen-containing gas in the presence of an oxidation catalyst and simultaneously reusing the catalyst. CONSTITUTION:2-Chloropropionaldehyde is oxidized with an oxygen-containing gas in the presence of an oxidation catalyst to product 2-chloropropionic acid useful as an intermediate for industrial and agricultural chemicals. In the process, a liquid phase, prepared by at least partially separating preferably the unreacted raw material and the aimed compound from the afore-mentioned reaction mixture and containing the above-mentioned catalyst is treated with active carbon to reuse the afore-mentioned catalyst without deteriorating activity in reusing the above-mentioned catalyst. Further, since the reaction temperature consequently need not be increased for maintaining the activity of the reused catalyst, selectivity for the aimed compound is improved. Furthermore, problems of environmental pollution, raw material loss, etc., caused by discarding of the catalyst can be improved.

Abstract: PURPOSE:To efficiently extract and separate high-purity pyruvic acid of excellent quality useful as a raw material for producing various medicines or amino acids from an aqueous solution containing the pyruvic acid in simple operation by using isopropyl acetate as an extracting solvent. CONSTITUTION:Isopropyl acetate in a volume of preferably 0.1-50times, especially preferably 0.5-5times based on water in an aqueous solution normally containing pyruvic acid is added to the aqueous solution containing the pyruvic acid at normally 10-80 deg.C, preferably 15-45 deg.C and the resultant mixture is stirred, distilled and then separated under ordinary pressure or more preferably under a reduced pressure of about 50-700mmHg to remove the isopropyl acetate. Thereby, the aimed pyruvic acid is extracted and separated by batch or continuous operation. Furthermore, the resultant pyruvic acid provides small load and loss thereof in a purification step.
