    Abstract: The invention relates to a method for producing 5-halo-2,4,6-trifluoroisophthalic acid of formula (I), wherein X represents F, Cl, Br, or I, by hydrolysis of 5-halo-2,4,6-trifluoroisophthalodinitrile of formula (II). Said invention is characterised in that in a first step, isophthalodinitrile (II) or a solution containing isophthalodinitrile (II) is reacted with a concentrated sulphuric acid at room temperature in order to form a 5-haIo-2,4,6-trifluoroisophthalodiamide of general formula (III), and is, subsequently, heated and in a second step, isophthalic acid (I) is produced after additional heating and addition of water.
