1. A compound represented by the general formula (1): RO (EO) n H (1) (wherein EO is ethylene oxide, R is an alkylphenyl having a linear or branched alkyl group having 4 to 14 carbon atoms). Base,
Or a linear or branched alkyl group having 8 to 36 carbon atoms, or an alkenyl group, and n is an integer of 1 to 100) in an aqueous solvent system at a reaction temperature of 30 to 100 ° C. and a reaction pressure of up to 10 atm. Under the conditions, palladium is used as the catalyst first component, and one or more kinds selected from the group consisting of selenium, tellurium, tin and bismuth is contained as the catalyst second component, and the catalyst second component and the first component are contained.
The ratio of the components (second component / first component) is 0.01 to 2.
It is 0, and is characterized by performing catalytic oxidation with oxygen or an oxygen-containing gas while adjusting the pH of the reaction system to 7.5 or higher in the presence of a supported catalyst in which a catalyst first component and a catalyst second component are previously supported on a carrier. And a method for producing a carboxylate.
