What is the preparation method of Ammonium 9,10-Dihydro-9, 10-Dioxoanthracene-1-Sulphonate
The preparation of 9,10-dihydro-9,10-dioxanthracene-1-ammonium sulfonate requires specific steps and conditions.
First of all, anthraquinone is used as the starting material, and the structure of anthraquinone is stable and has a specific chemical activity check point, which is suitable for subsequent reactions. In a specific reaction vessel, anthraquinone is mixed with fuming sulfuric acid. This fuming sulfuric acid needs to be taken in exact proportions, and its concentration and dosage have a great influence on the reaction process and product purity. After mixing, moderate heating is applied to maintain a certain temperature range. This temperature must be precisely controlled. If it is too low, the reaction will be slow, and if it is too high, it will cause side reactions to occur. After this step, the 1-position of anthraquinone can be introduced into the sulfonic acid group to generate 9,10-dihydro-9,10-dioxo-anthracene-1-sulfonic acid.
Then, after the above reaction is completed and the product is cooled, an appropriate amount of ammonia water is slowly added. The concentration and drip rate of ammonia water also need to be strictly controlled. Adding ammonia water too fast or too concentrated may cause local reactions to be violent and affect the uniformity of the product. The purpose of this step is to neutralize 9,10-dihydro-9,10-dioxanthracene-1-sulfonic acid with ammonia to generate 9,10-dihydro-9,10-dioxanthracene-1-sulfonate ammonium.
After the reaction is completed, the product or impurities need to be purified. The method of recrystallization can be used to select a suitable solvent, which needs to have a significant difference in the solubility of the product with temperature. The product is dissolved in a hot solvent, filtered while hot to remove insoluble impurities, and then slowly cooled to allow the product to crystallize and precipitate. After filtration, washing, drying and other operations, pure 9,10-dihydro-9,10-dioxyanthracene-1-ammonium sulfonate can be obtained. Throughout the preparation process, precise control of the proportion of raw materials, reaction temperature, time and each operation step is the key to obtaining high-purity products.
