To prepare Sodium + 3,5 - bis (acetylamino) - 2,4,6 - triiodobenzoate Dihydrate (3,5 - bis (acetylamino) - 2,4,6 - sodium triiodobenzoate dihydrate), the preparation method is as follows:
First take an appropriate amount of 3,5 - diaminobenzoic acid and place it in the reaction kettle. Using an appropriate amount of glacial acetic acid as the solvent, slowly add acetic anhydride. During this process, pay close attention to the reaction temperature to control the temperature within a moderate range, so that acetic anhydride can fully react with 3,5 - diaminobenzoic acid to obtain 3,5 - bis (acetylamino) benzoic acid. This reaction lasts for several hours. After the reaction is completed, the product is separated, washed and dried to obtain pure 3,5-bis (acetamido) benzoic acid.
Then, put the obtained 3,5-bis (acetamido) benzoic acid into another reaction vessel and dissolve it with an appropriate solvent. Slowly add iodine and an appropriate amount of oxidant, which can be hydrogen peroxide. During the reaction, continue to stir to facilitate the uniform progress of the reaction, and strictly control the reaction conditions, such as temperature, pH, etc. After this reaction, 3,5-bis (acetamido) -2,4,6-triiodobenzoic acid can be obtained. After the reaction is complete, the pure 3,5-bis (acetylamino) -2,4,6-triiodobenzoic acid is obtained by separation and purification.
Finally, take an appropriate amount of 3,5-bis (acetylamino) -2,4,6-triiodobenzoic acid, dissolve it in an appropriate amount of water, add an appropriate amount of sodium hydroxide, adjust the pH of the solution, and make it a sodium salt. After concentration, crystallization and other processes, 3,5-bis (acetylamino) -2,4,6-triiodobenzoic acid sodium dihydrate crystals can be obtained. After the crystals are separated, washed and dried, the desired product is obtained. The whole process requires fine operation, paying attention to the reaction conditions of each link, in order to obtain pure and high-yield products.

This product is called "3,5-bis (acetamido) -2,4,6-triiodobenzoate sodium dihydrate". Its storage conditions are quite important, which is related to the quality and stability of this product.
This product should be stored in a dry, cool and well-ventilated place. A dry environment can prevent it from deliquescence due to water vapor erosion and cause changes in its composition. Cool conditions can avoid chemical reactions caused by high temperatures, because it may decompose or deteriorate at high temperatures. Well-ventilated air can circulate around it to disperse moisture and heat that may accumulate.
Furthermore, it needs to be separated from other chemicals when storing. Due to its chemical properties or reactions with other substances, it can affect its own quality. The storage container should also be suitable as a sealed container to better maintain its state and prevent contact with outside air, water vapor, etc. In this way, it can ensure that "3,5-bis (acetamido) -2,4,6-triiodobenzoate sodium dihydrate" maintains good properties during storage for subsequent use.

Sodium 3,5 - bis (acetylamino) -2,4,6 - triiodobenzoate Dihydrate (3,5 - bis (acetylamino) -2,4,6 - sodium triiodobenzoate dihydrate) When using, many matters should be paid attention to.
