What are the preparation methods of N, N '-Bis [6- (1-Naphthol-3-Sulfonic Acid) ] Urea?
To prepare N% 2CN% 27-bis [6- (1-naphthol-3-sulfonic acid) ] urea, there are three methods. First, take 1-naphthol-3-sulfonic acid and urea as materials, add an appropriate amount of catalyst in a specific solvent, and control the temperature. Among them, the solvent is preferably a polar organic solvent, such as dimethyl sulfoxide, because it can increase the solubility of the reactants and facilitate the reaction. The catalyst can be selected from protonic acids, such as p-toluenesulfonic acid, the dosage is about 2% - 5% of the total reactant, the temperature should be 120-150 ℃, the reaction lasts 4-6 hours, and stirring is required during this period to promote the material to mix evenly and improve the reaction efficiency.
Second, 1-naphthol-3-sulfonic acid is first made into an active intermediate, such as acid chloride, and then reacted with urea. 1-naphthol-3-sulfonic acid is treated with thionyl chloride to obtain acid chloride. This process is carried out at low temperature (0-5 ℃) and protected by inert gas to prevent side reactions. After that, the acid chloride is dropped into the reaction system containing urea. The system uses triethylamine as the acid binding agent, and the target product can be obtained when the reaction is 2-3 at room temperature. Although this route is a little complicated, the product purity is high.
Third, with the help of phase transfer catalysis. In the water-organic phase mixed system, quaternary ammonium salts, such as tetrabutylammonium bromide, are used as phase transfer catalysts to react 1-naphthol-3-sulfonic acid with urea. The aqueous phase provides an ionic environment, and the organic phase dissolves the organic reactants, and the phase transfer catalyst shuttles through it to transfer ions and promote the reaction. When the reaction temperature is about 60-80 ℃, and the reaction is 3-5, this method is easy to operate and can avoid the use of a large amount of organic solvents.
How safe is N, N '-Bis [6- (1-Naphthol-3-Sulfonic Acid) ] Urea?
N% 2CN% 27 -bis [6- (1-naphthol-3-sulfonic acid) ] urea, the safety of this substance is related to many aspects.

However, looking at past studies of similar chemicals, some of them have similar structures, which may pose potential hazards to biological organisms. Such as entering the body of organisms, or interacting with key components of cells, interfering with normal physiological processes, causing cell damage and even lesions.
Talk about environmental effects, if it flows into the natural environment, in water bodies, or changes the chemical properties of water bodies, it will affect the survival and reproduction of aquatic organisms. In the soil, or affect the structure and function of the soil microbial community, and then affect the balance of the soil ecosystem.
In terms of operation safety, if its properties are powdery, it will be raised during operation, or enter the human body through the respiratory tract, causing irritation to respiratory mucosa. If it is liquid, contact with the skin, or cause skin allergies, corrosion and other conditions.
Therefore, when using this substance, caution must be taken.
