Preparation method for ioversol

The invention provides a preparation method for ioversol. Specifically speaking, the method comprises the following steps: (1) performing an alkylation reaction on 5-chloracetyl amino-N,N'-bi-(2,3- dyhydroxyl propyl)-2,4,6-triiodo-1,3-phthalic diamide and chlorethyl alcohol under an alkaline condition; (2) hydrolyzing through sodium acetate to obtain the ioversol. A container of which the inner wall is coated with a corrosion-resistant coating is used in the reactions of the former two steps, and the water with the iron content of below 0.05 ppm is used. The method can effectively avoid the production of impurities which are difficult to remove, and is suitable for industrial production.
