What is the production method of 6-Nitro-1-Diazo-2-Naphthol-4-Sulfonic Acid?
The method of preparing 6-nitro-1-diazo-2-naphthol-4-sulfonic acid has been around since ancient times. In the past, to make this substance, the first thing to do was to use naphthalene as a base and perform sulfonation. Take naphthalene and place it in a specific vessel, add appropriate sulfonating reagents, such as sulfuric acid, etc., and skillfully control the temperature to make the naphthalene react moderately with sulfuric acid. In this process, it is necessary to pay attention to the fluctuation of temperature, neither too high nor too low. If the cap temperature is too high, side reactions will occur, and if it is too low, the reaction will be slow.
Wait for sulfonation to be completed, and the obtained product will be nitrified again. Take nitrides such as mixed acids of nitric acid and sulfuric acid, slowly add sulfonated products, and stir constantly to make the reaction uniform. This nitrification step requires special caution, because nitric acid has strong oxidizing properties, if you don't pay attention, accidents will occur.
Nitrification products are then changed to diazotization. Select appropriate diazotization reagents, such as sodium nitrite, under a specific acid-base environment, and make them react properly with nitrification products to obtain 6-nitro-1-diazo-2-naphthol-4-sulfonic acid. The whole process is interconnected, and any link is wrong, which is difficult to achieve. The operator must have skilled skills and always pay attention to the details of the reaction before he can obtain pure 6-nitro-1-diazo-2-naphthol-4-sulfonic acid.
