Abstract: An acid composition comprising 2-formyl-furan-5-carboxylic acid and 2,5-furandicarboxylic acid is purified in a process which comprises; contacting the acid composition with an alcohol to obtain an esterified composition; and separating the ester of 2-formyl-furan-5-carboxylic acid from the esterified composition to obtain a purified esterified product; and contacting the purified esterified composition with water for saponification or hydrolysis, to obtain a product composition, comprising 2,5-furandicarboxylic acid and a reduced amount of 2-formyl-furan-5-carboxylic acid.
