The method of preparing 2- [ (4-hydroxy-9,10-dioxo-9,10-dihydroanthracene-1-yl) amino] -5-methylbenzenesulfonate sodium is described below.
First take an appropriate amount of 4-hydroxyanthraquinone and place it in a clean reaction vessel. Another 5-methylbenzenesulfonic acid compound containing amino groups is prepared and slowly added to the reaction vessel. Add a specific catalyst, which must be able to effectively promote the reaction of the two and have good selectivity and activity.
Subsequently, an appropriate amount of organic solvent is injected into the vessel to fully dissolve the reactants to form a uniform reaction system to facilitate the uniform progress of the reaction. Set the appropriate reaction temperature and pressure. Usually, the temperature needs to be maintained within a certain range. If the temperature is too high or side reactions occur, if it is too low, the reaction rate will be too slow. The pressure also needs to be precisely controlled to create the best reaction environment.
During the reaction process, continuous stirring is required to ensure that the reactants are in full contact and accelerate the reaction process. When the reaction is in progress, the reaction process can be closely monitored, and the degree of reaction can be known in real time by means such as thin-layer chromatography.
After the reaction reaches the desired level, stop the reaction. Then, the reaction mixture is separated and purified. First, insoluble impurities are removed by filtration. Then, the target product is enriched in a specific phase with a suitable solvent. Then by means of distillation, crystallization, etc., the product is further purified to obtain high-purity 2- [ (4-hydroxy-9,10-dioxo-9,10-dihydroanthracene-1-yl) amino] -5-methylbenzenesulfonate sodium.
The whole preparation process requires strict control of the conditions of each link to ensure that the operation is fine and correct, in order to obtain high-quality products.
