Procedure
A stirred slurry of 5-acetamido-2,4,6-triiodo-N-[tris(acetoxymethyl)methyl]isophthalamic acid (4.15 g., 5 mol.) in water (20 ml.) was carefully neutralized by dropwise addition of 1 N sodium hydroxide solution (5.00 ml.) so that the pH of the solution never exceeded 7.00. The resulting clear solution (pH 6.98) was concentrated under reduced pressure at room temperature (25°, 20 mm. to 0.1 mm.) and dried overnight in vacuo (0.1 mm.) to yield the salt indicated in the caption as a white powder (4.2 g.). The solubility of this powder in water is greater than or equal to 100% (wt/vol).
