2% 2C2% 27 - disulfanediylbis%281%2C3 + - benzothiazole% 29, the Chinese name is often dibenzothiazole disulfide. The physical properties of this substance are as follows:
Its appearance is mostly light yellow to off-white powder, light in color and fine in quality. At room temperature, it is quite stable, and the smell is slight, which is barely noticeable. The melting point is high, about 176 ° C to 181 ° C. When heated, it melts into a liquid state in this temperature range.
Its density is moderate, about 1.52 grams per cubic centimeter. It is insoluble in water and is placed in water. If sand sinks to the bottom, it is incompatible with water. However, in some organic solvents, it can show a certain solubility, such as acetone, benzene, etc., which can be dissolved to form a uniform solution.
In addition, its dust is in the air, if the concentration is appropriate, in case of open flame, hot topic and other conditions, or there is a risk of explosion. And although this material is stable at room temperature, if exposed to strong light, high humidity or contact with specific chemicals, it may slowly undergo chemical changes, affecting its original properties.
It can be seen from the above that 2% 2C2% 27 - disulfanediylbis%281%2C3 + - benzothiazole% 29 has unique physical properties. It has specific uses and precautions in many fields such as industrial production and chemical applications due to these characteristics.

To prepare 2,2 '-disulfide-bis (1,3-benzothiazole), the method is as follows:
Usually 2-mercaptobenzothiazole is used as the starting material. In a suitable reactor, add an appropriate amount of 2-mercaptobenzothiazole, and add a suitable solvent, such as ethanol and acetone, to fully dissolve it to form a uniform solution.
Then, slowly add the oxidizing agent. Commonly used oxidizing agents are hydrogen peroxide, ammonium persulfate, etc. When adding, pay attention to the rate and keep stirring to mix the reaction system evenly and make the reaction proceed smoothly.
When reacting, temperature control is crucial. In general, it is advisable to maintain between room temperature and 50 ° C. If the temperature is too high, side reactions may increase; if the temperature is too low, the reaction rate will be delayed.
During the reaction process, the phenomenon can be observed. As the reaction advances, the color state of the solution may change. The reaction process can be monitored by means of thin layer chromatography (TLC) to determine the degree of completeness of the reaction.
After the reaction is completed, cool the reaction liquid. Then, separate and purify. The common method is filtration. If the product is solid, it can be obtained through filtration. Then by the method of recrystallization, the crude product is recrystallized with a suitable solvent, such as ethanol-water mixed solvent, etc., to remove impurities and obtain pure 2,2 '-disulfide (1,3-benzothiazole). After drying, the finished product can be obtained. Throughout the preparation process, attention must be paid to the specifications of operation to ensure safety and product quality.

2% 2C2% 27 - disulfanediylbis%281%2C3 + - benzothiazole% 29, that is, dibenzothiazole disulfide. During the use of this product, many matters need to be paid attention to.
First, safety is the first priority. Dibenzothiazole disulfide has certain toxicity. When operating, strictly follow safety procedures. If it accidentally touches the skin or eyes, rinse with plenty of water immediately, and seek medical treatment if necessary. The use site should also be well ventilated to prevent inhalation of its dust or volatile gas, which can damage the respiratory system.
Second, storage is also important. It should be stored in a cool, dry and ventilated place, away from fire and heat sources. Because of its nature or affected by temperature and humidity, if it is improperly stored or causes quality changes, it will affect the use effect.
Third, the dosage of use needs to be precisely controlled. In different application scenarios, the dosage required varies. If the dose is too small, it may be difficult to achieve the desired effect; if the dose is too high, it may cause adverse consequences, such as affecting product performance. Therefore, before use, the appropriate dosage should be determined after rigorous testing.
Fourth, compatibility cannot be ignored. When sharing with other chemical substances, its compatibility must be considered. If it is incompatible with certain substances, or causes chemical reactions, damage product quality, and even cause safety accidents.
Fifth, waste disposal must be in compliance. After use, residues and waste should be properly disposed of in accordance with relevant laws and regulations, and should not be discarded at will to avoid polluting the environment.
All of these are to be used when using 2% 2C2% 27 - disulfanediylbis%281%2C3 + - benzothiazole% 29, so as to ensure the safe and effective use.
