To prepare Trisodium (3E) -5-Hydroxy-4-Oxo-3- [ (4-Sulfonatophenyl) Hydrazono] -3,4-Dihydronaphthalene-2, 7-Disulfonate, the method is as follows:
First take an appropriate amount of 5-Hydroxy-4-Oxo-3,4-Dihydronaphthalene-2,7-Disulfonic Acid and place it in a clean reaction vessel. This is the basic raw material for the initiation of the reaction, and its quality and purity have a great influence on the quality of the final product, so it needs to be carefully selected and prepared.
Next, slowly add (4-Sulfonatophenyl) Hydrazine. When adding, pay attention to the speed and stirring strength. Excessive speed or uneven stirring may cause insufficient reaction or the growth of side reactions. The purpose of stirring is to make the two fully blend and accelerate the reaction process.
During the reaction process, precise regulation of temperature and pH is the key. Appropriate temperature can make the reaction proceed at an appropriate rate. If the temperature is too high, the reaction will be excessive and impurities will be easily generated; if the temperature is too low, the reaction will be slow and take a long time. The control of pH is also related to the direction and efficiency of the reaction. Usually with the help of specific acid-base regulators, the pH of the reaction system is maintained within a predetermined range.
After the reaction is roughly completed, a series of purification steps are required. This step is designed to remove impurities generated during the reaction process to improve the purity of the product. Methods such as crystallization, filtration, and washing can be used. The crystallization process requires controlling the ratio of cooling rate to solvent to allow the product to precipitate in pure crystal form. When filtering, choose a filter material with suitable pore size to ensure effective separation of impurities. Washing requires selecting a suitable solvent to wash away impurities without excessive loss of the product.
After various operations, carefully collect and dry the product, and finally obtain Trisodium (3E) -5-Hydroxy-4-Oxo-3- [ (4-Sulfonatophenyl) Hydrazono] -3, 4-Dihydronaphthalene-2, 7-Disulfonate. During the preparation process, each step needs to be carefully operated, and a slight error may affect the quality and yield of the product.
