Abstract
A process for the preparation of the dichloride of 5- amino-2,4,6-triiodoisophthalic acid comprising the heterogeneous phase reaction between 5-amino-2,4,6- triiodiisophthalic acid with a mixture of thionyl chloride and a straight or branched C7-C16 hydrocarbon or toluene, in the presence of a catalytic quantity of a tertiary amine, is described.
