Sodium Diphenylamine - 4 - Sulfonate

The method of preparing p-sulfonic acid-based azobenzene sodium salt is quite delicate. In the past, many wise men studied the way of chemistry very deeply, but today, with the description of ancient methods, Chen Qi is general.
First of all, the raw materials need to be prepared, benzene, sulfuric acid, nitric acid, sodium hydroxide, etc., all need to be pure and free of impurities, which is the basis for preparation. First, the benzene and concentrated sulfuric acid are co-heated to carry out the sulfonation reaction. This step requires appropriate temperature control, about one hundred and fifty to one hundred and eighty degrees Celsius, and the benzene sulfonic acid can be obtained after a few hours.
Then, the mixed acid of benzenesulfonic acid with nitric acid and sulfuric acid is combined. This is the process of nitrification. The temperature should be at 30 to 40 degrees Celsius. Be careful to control it so that the counterposition of benzenesulfonic acid is introduced into the nitro group to obtain p-nitrobenzenesulfonic acid.
Then, the p-nitrobenzenesulfonic acid is reduced with iron powder and hydrochloric acid as reducing agent to obtain p-aminobenzenesulfonic acid. This step is violent and needs to be slowed down. The temperature is moderate and not out of control.
Then the p-aminobenzenesulfonic acid is combined with sodium nitrite and hydrochloric acid at low temperature, about 0 to 5 degrees Celsius, to form a diazonium salt. This diazonium salt
Finally, the diazonium salt is coupled with phenol in an alkaline environment, and an appropriate amount of sodium hydroxide is added to adjust the pH to form an azo compound. After separation and purification, it is washed many times with ethanol, water and other solvents. After drying, p-sulfonic acid-based azobenzene sodium salt can be obtained. This preparation method is crucial step by step, and it is necessary to be careful to obtain a pure product.
