Abstract

PURPOSE: To obtain a carboxylic acid advantageously, by isomerizing a formate in the presence of a catalyst consisting of (a) metal palladium or palladium compound, (b) an alkyl halide or hydrogen halide, and (c) a base, and carbon monoxide.
CONSTITUTION: A formate shown by the formula HCOOR(R is straight-chain or branched-chain alkyl, etc.) is isomerized in the presence of a catalyst consisting of (i) metal palladium or palladium compound, (ii) alkyl halide or halogenated hydrocarbon, and (iii) a base (e.g., an organic base, e.g., amine, amide, phosphine, etc.) and carbon monoxide preferably at 150W250°C and under a carbon monoxide partial pressure of 30W150kg/cm2 to give a carboxylic acid shown by the formula RCOOH in high conversion and high selectivity by using the relatively inexpensive catalyst. Preferably an amount of (i) calculated as Pd is 1W50mg atom per mole of the raw material, and an amount of (ii) is 1W100mol and an amount of (iii) is 1W1000mol per g atom of (i) respectively.
