PROBLEM TO BE SOLVED: To provide a method for producing a polycarboxylic acid metal complex useful as an adsorbent in a short time with a high yield and high productivity. A polycarboxylic acid such as trans-1,4-cyclohexanedicarboxylic acid, terephthalic acid, trans, trans-4,4′-bicyclohexyldicarboxylic acid, nuclear hydrogenated 2,6-naphthalenedicarboxylic acid and copper, A metal salt such as rhodium or nickel is reacted in the presence of a solvent while controlling the temperature range in a relatively high temperature range of 120 ° C. or higher and 270 ° C. or lower. In this method, a high concentration of carboxylic acid can be used as a raw material, and it is not necessary to use an additive such as formic acid. [Selection figure] None |
