Abstract:
The invention describes a process for the purification of iodinated aryl compounds where the purification is performed by continuous crystallization of a crude product in a solvent with removal of at least a fraction of the solvent. The continuous crystallization process is performed in one or more crystallizers at the boiling point of the content of the crystallizer.
