What are the preparation methods of 4- (Phenylamino) Benzenesulfonate

The preparation method of 4- (anilinyl) benzenesulfonate has been known for a long time, and there are many methods. Let me tell you one by one.
First, it can be prepared by reacting aniline with p-sulfobenzyl chloride under suitable conditions. Prepare the refined aniline first, which is active, and p-sulfobenzyl chloride needs to be pure and free of impurities. Place the two in a reactor, and choose a mild organic solvent, such as dichloromethane, to help it fully contact. Control the temperature in a moderate range, or add it slowly under an ice bath to prevent overreaction. During the process, it is necessary to constantly stir to mix the reactants evenly. After the reaction is completed, the crude product is obtained by extraction, washing, drying and other steps, and then purified by recrystallization to obtain a high purity 4- (anilinyl) benzenesulfonate.
Second, p-aminobenzenesulfonic acid reacts with halogenated benzene under the catalysis of a base. Take p-aminobenzenesulfonic acid, which is acidic, and first neutralize with the base to form a salt to increase its solubility. Halogenated benzene such as bromobenzene, chlorobenzene, etc., also need to be dried without moisture. Choose a suitable base, such as potassium carbonate, sodium carbonate, etc., in an organic solvent such as N, N-dimethylformamide, and heat and reflux. This reaction needs to pay attention to the activity of halogenated benzene. If the activity is not good After the reaction is completed, the target product is obtained by post-treatment, separation and purification.
Third, it is prepared by the coupling reaction of diazonium salts. The p-aminobenzenesulfonic acid is first prepared as a diazonium salt, and the p-aminobenzenesulfonic acid can be obtained by treating the p-aminobenzenesulfonic acid with sodium nitrite and inorganic acid at low temperature. Aniline derivatives are used as coupling components and react with the diazonium salt under appropriate pH conditions. This reaction requires strict temperature and pH requirements. If the temperature is too high or the pH is not appropriate, it is easy to cause side reactions to occur. After the reaction is completed, it is separated and refined to obtain 4- (aniline
These methods have their own advantages and disadvantages. According to actual needs, factors such as raw material availability, cost, yield and purity should be weighed, and an appropriate method should be selected to prepare 4- (anilinyl) benzenesulfonate.

What are the storage conditions for 4- (Phenylamino) Benzenesulfonate?

4- (phenylamino) benzenesulfonate is one of the chemical substances. Its storage conditions are essential to the properties and stability of this substance.
This substance should be placed in a cool and dry place. Cover a cool place to reduce its changes due to excessive temperature. If it is at high temperature, it may cause its chemical structure to change, its activity to change, or even decompose, damaging its quality and function. Dry places are also important because they are afraid of moisture. Moisture invades it, or causes it to deliquescent, chemically reacts with water, causing it to deteriorate.
and should be sealed and stored. The reason for sealing is to prevent it from contacting various components in the air, such as oxygen, carbon dioxide, etc. Oxygen or its oxidation, carbon dioxide or chemical reactions with it are not conducive to its preservation. It must also be kept away from fire and heat sources. Fire and heat can both stimulate its chemical reactions or cause danger, such as combustion and explosion.
As for the storage place, it should be selected in a well-ventilated place. With good ventilation, air circulation can remove harmful gases that may be generated, keep the storage environment safe, and also help maintain a suitable temperature and humidity. And it must be stored separately from oxidizing agents, acids, bases, etc. These substances, or with 4 - (phenylamino) benzenesulfonate, react violently, creating an unpredictable risk.
All these storage conditions are to protect the properties of 4- (phenylamino) benzene sulfonate, ensure its quality, and avoid danger. Those who use it must not ignore it.
