Saturated vapor pressure (kPa ,60ºCAmino-2,4,6-Sodium triiodobenzoate (see02780) acetylation Obtain: Add acetic anhydride and sulfuric acid to the reaction tank successively, and cool to 40℃Add later3-Amino-2,4,6-Sodium triiodobenzoate. The temperature rises to 80℃80℃Reaction3hours. Cool to room temperature, filter, and wash with distilled water to obtain crude acetoiodobenzene acid. Add water and EDTAStir1hours, filter, rinse with water4 times. Then add acetoiodobenzoic acid into the tank and adjust the pH with ammoniapHTO8.5. Filter, use 95%Soak and wash repeatedly with ethanol, filter out the ethanol, and obtain ammonium aceiodobenzoate. Dissolve it in distilled water, add activated carbon to decolorize and filter, and use filtrate with 3NHydrochloric acid adjustmentpHto1, then filter, use50℃Wash with hot distilled water until there is no chloride ion, After drying, acetoiodobenzoic acid is obtained.
