zinc2-benzothiazolethiolate

The chemical structure of zinc (II) -benzothiazole thiol salt is formed by combining zinc ions with benzothiazole thiol root ions. Benzothiazole thiol root ions, derived from benzothiazole mercaptan. This mercaptan contains a benzothiazole ring, which is fused by a benzene ring with a thiazole ring, and the nitrogen and sulfur atoms in the thiazole ring are interphase. The thiol group (-SH) is connected to the benzothiazole ring. Under certain conditions, the hydrogen atom of the thiol dissociates to form the benzothiazole mercaptan anion (-S -).
Zinc ions are usually divalent (Zn ²), have empty orbitals, and can accept electron pairs. The sulfur atom of the benzothiazole thiol anion contains lone pairs of electrons, which can provide coordination with zinc ions. In this way, zinc ions and the benzothiazole thiol anion are connected by coordination bonds to achieve charge balance and stable structure.
Its structure may be a core solo complex, a zinc ion is coordinated with several benzothiazole thiol anions; or a polynuclear structure is formed, and zinc ions are bridged by thiol anions. The specific structure is affected by factors such as reaction conditions, the proportion of reactants and solvents. For example, in a specific solvent, solvent molecules may participate in coordination to change the structure and stability of the complex. The properties of this chemical structure are of great significance in the fields of materials science, catalysis, and biomedicine, affecting their physical, chemical, and biological activities.

Zinc 2-benzothiazole mercaptan has a wide range of uses and is used in all kinds of industries.
First, in the rubber industry, it is a key vulcanization accelerator. Vulcanization is the process of transferring rubber from a linear polymer to a three-dimensional network structure, which can increase the strength, wear resistance and aging resistance of rubber. Zinc 2-benzothiazole mercaptan can accelerate the vulcanization process, reduce the time and temperature required for vulcanization, improve the efficiency of production, and optimize the physical and mechanical properties of vulcanized rubber, making the product more durable.
Second, in the field of coatings, it can be used as a preservative. Coatings are applied to the surface of objects to resist external erosion. Zinc 2-benzothiazole thiol salt can delay the rate of corrosion of the object covered by the coating by its own characteristics. Whether it is metal oxidation and rust, or other materials due to environmental factors that cause performance deterioration, it can play a protective role, increase the protection period of the coating, and maintain the integrity and aesthetics of the surface of the object.
Third, in the plastics industry, it can be used as a stabilizer. Plastics are easily degraded by light, heat, oxygen, etc. during processing and use, resulting in poor performance. Zinc 2-benzothiazole thiol salt can inhibit such degradation reactions, keep plastics stable during high temperature processing, and in daily use environment, slow down its aging rate, prolong the service life of plastic products, and broaden its application range.
Fourth, it is also useful in lubricating oil additives. Lubricating oil needs to reduce friction and wear between parts when operating mechanical equipment. Adding zinc 2-benzothiazole thiol salt can form a protective film on the metal surface, reduce the friction coefficient, improve the anti-wear performance of lubricating oil, reduce the loss of mechanical parts, ensure the smooth and efficient operation of equipment, and prolong the service life of equipment.

The preparation method of zinc-2-benzothiazole thiol salt is as follows:
First take an appropriate amount of 2-mercaptobenzothiazole and place it in a reaction vessel. React with an alkaline substance, such as an aqueous solution of sodium hydroxide or potassium hydroxide. This reaction needs to be carried out at a moderate temperature and under stirring conditions, so that 2-mercaptobenzothiazole fully interacts with the base to form a corresponding salt solution.
Take another zinc salt, such as an aqueous solution of zinc sulfate or zinc chloride, and slowly drop it into the above-prepared salt solution. When adding dropwise, continue to stir so that the two can be evenly mixed and fully reacted. During this reaction, zinc-2-benzothiazole mercaptan will precipitate out.
After the reaction is completed, the mixture is filtered to separate the precipitation. Wash the precipitation repeatedly with an appropriate amount of deionized water to remove impurities. Then, the washed precipitation is placed in an oven and dried at a suitable temperature to obtain the zinc-2-benzothiazole mercaptan product. During the operation, pay attention to the control of temperature, the proportion of reactants and the reaction time to ensure the purity and yield of the product.

Zinc 2-benzothiazole thiol salt, this is a chemical substance. Its physical properties are quite important and are related to many practical applications.
First of all, the appearance is usually white to light yellow powder, and the texture is fine, like light dust. This form makes it easy to disperse and mix in many chemical reactions and industrial processes, and can evenly participate in various processes.
Besides solubility, in organic solvents, such as toluene and acetone, it has a certain solubility. This property makes it easy for it to be used as an additive or reaction intermediate in organic systems, and it can smoothly blend and react with other organic components. However, its solubility in water is extremely low, which limits its application in aqueous systems, but also gives it potential value in some waterproof and moisture-proof products.
Thermal stability is also worth mentioning. In the moderate temperature range, the structure is quite stable and can withstand a certain amount of heat without decomposition. However, when the temperature rises to a certain threshold, the molecular structure will change, which in turn affects its chemical activity and physical properties. This property needs to be carefully considered during high temperature processing to avoid damage to product performance.
In addition, the density of zinc 2-benzothiazole thiol salt also has its own characteristics. The relative density is moderate, which affects its dispersion and precipitation behavior in different media. In some suspension systems, a moderate density ensures that it does not settle too quickly, maintaining the uniformity and stability of the system.
In short, these physical properties of zinc 2-benzothiazole mercaptan are interrelated, which determines its application mode and effect in rubber, plastics, coatings and many other fields.

Zinc 2-benzothiazole thiol salt, when using, there are various precautions to keep in mind.
First, it is related to safety protection. This substance may be potentially harmful to the human body, such as contact with the skin, or cause allergies and irritations. Therefore, when operating, it is necessary to wear suitable protective equipment, such as gloves, goggles, protective clothing, etc., to prevent skin and eye contact. If you come into contact, rinse with plenty of water as soon as possible, and seek medical treatment if necessary.
Second, storage should not be ignored. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Due to its chemical properties or environmental factors, improper storage or deterioration, affecting the use effect, and even creating potential safety hazards. At the same time, it needs to be stored separately from oxidants, acids, etc., to avoid chemical reactions caused by mixed storage.
Third, during use, precise control of the dosage is the key. Accurate measurement should be made according to specific needs and reaction requirements. If the dosage is too small, it may be difficult to achieve the expected effect; if the dosage is too large, it may not only cause waste, but also lead to side reactions, which may have adverse effects on subsequent products or processes.
Fourth, fully understand its chemical properties and reaction mechanism. Only by knowing its reaction behavior under different conditions can we reasonably plan the use steps and reaction environment to ensure the smooth use process and achieve the expected purpose. When launching new applications or reactions, it is recommended to conduct small-scale trials first to evaluate their feasibility and effectiveness.
