摘要： 6-Iodoethylated starch and process for preparing the same are disclosed. The 6-idodethylated starch contains one iodine attached per 5 glucose units. Said compound is useful as a contrast agent for X-ray examination, especially for opacifying the vascular os lymphatic vessel. Said compound is produced by reacting 6-hydroxyethylated starch with N-iodosuccinimide in the presence of triphenylphosphine.
