This is a vulcanization accelerator, which can speed up the vulcanization rate of rubber and make the production of rubber products more efficient. During the vulcanization process, it can reduce the vulcanization temperature and reduce the vulcanization time, which can not only save energy, but also improve production efficiency.

It can also improve the physical and mechanical properties of rubber products. Through its action, the tensile strength, wear resistance and tear resistance of vulcanized rubber have been significantly improved. Taking tires as an example, after using this accelerator, tires are more wear-resistant and their service life can be extended, which makes a great contribution to driving safety.

Furthermore, the substance has a good control effect on the scorch time of rubber. Scorching is an undesirable phenomenon of early vulcanization before vulcanization in rubber processing. N-tert-butylbenzothiazole-2-sulfoamide can prolong the scorch time appropriately, so that the rubber has more abundant operating time during processing, reduce the waste rate, and ensure the smooth progress of production.

In the production of many products in the rubber industry, such as various tires, hoses, tapes, seals, etc., N-tert-butylbenzothiazole-2-sulfoamide is indispensable, which is of great significance for improving the quality and production efficiency of rubber products.

What is N-tert-butylbenzothiazole-2-sulphenamide production method?

N-tert-butyl benzothiazole-2-sulfinamide, there are various ways to prepare it. Usually benzothiazole-2-mercaptan and tert-butylamine are used as starting materials, accompanied by appropriate catalysts, and under suitable reaction conditions.

Prepare benzothiazole-2-thiol, which can be obtained from benzothiazole through specific reaction conversion. Tert-butylamine also needs to be carefully selected to ensure its purity.

Put both into a reactor and add an appropriate amount of catalyst, such as some kind of metal salt or organic base. Temperature control is crucial, often maintained in a specific range, such as 50 to 100 degrees Celsius. The reaction time also needs to be carefully observed, depending on the reaction process, usually several hours or even ten hours.

During the reaction, the molecules interact, and the sulfur atom of benzothiazole-2-thiol is connected to the nitrogen atom of tert-butylamine to form N-tert-butyl benzothiazole-2-sulfinamide.

After the reaction is completed, the product is separated and purified. The method of distillation, crystallization or column chromatography is commonly used to obtain pure N-tert-butylbenzothiazole-2-sulfinamide in addition to untreated raw materials, by-products and catalyst residues.

This method has been tried and improved many times in the chemical industry, and strives to be efficient and pure to meet the needs of different industries for N-tert-butylbenzothiazole-2-sulfinamide.

What are the physical and chemical properties of N-tert-butylbenzothiazole-2-sulphenamide

N-tert-butylbenzothiazole-2-sulfenamide is a chemical material, and its physical and chemical properties are well-researched. Under normal temperature, this substance is mostly in the state of white or off-white powder, and it looks fine and uniform, without variegated colors. Smell it, the breath is quite slight, and there is no pungent or unpleasant smell.

Its melting point is moderate, about 104 ° C to 110 ° C. This characteristic has a great impact on the handling and handling of materials in specific industrial processes. And it has good thermal stability. It is not easy to decompose and deteriorate due to heat in the general processing temperature range, which can ensure the stability of product quality.

When it comes to solubility, it exhibits a certain solubility in common organic solvents such as benzene, toluene, chloroform, etc., and can be soluble in such solvents to form a uniform solution. This point is of great significance when preparing solution-type products or participating in specific chemical reactions. However, its solubility in water is poor and almost insoluble, which makes it exhibit unique behavior in systems involving aqueous phases.

Furthermore, N-tert-butylbenzothiazole-2-sulfenamide has relatively stable chemical properties, but under specific conditions, such as strong acids, strong bases or high temperatures and strong oxidants, it can also undergo chemical reactions, showing a chemically active side. These physical and chemical properties are intertwined, which determines that it can be used as a vulcanization accelerator in the rubber industry and other fields to play a unique role and help improve the performance of rubber products.

N-tert-butylbenzothiazole-2-sulphenamide what are the precautions during use

For N-tert-butylbenzothiazole-2-sulfinamide, there are many matters that need to be paid attention to when using it.

First of all, this agent is a rubber accelerator with high activity. When using it, be sure to precisely control the dosage. If the dosage is too small, the promotion effect will not be good, the rubber vulcanization process will be slow, and the physical properties of the product will not meet expectations; if the dosage is too much, the vulcanization speed will be too fast, which will cause the rubber to scorch and affect the quality and processing performance of the product.

Second, it is quite sensitive to temperature. If the temperature rises, the promotion effect will be intensified. Therefore, in the mixing, vulcanization and other processes, the temperature needs to be closely monitored. If the temperature is too high, it is easy to cause early vulcanization, that is, scorching phenomenon, resulting in bubbles and glue shortage in rubber products; if the temperature is too low, the vulcanization reaction is slow and the production efficiency is low.

Furthermore, the compatibility with other additives also needs to be cautious. Different additives may have synergy effects or antagonistic effects. When sharing with some active agents, antioxidants, etc., it is necessary to know their interactions in advance and match them reasonably in order to optimize the performance of rubber products. For example, if mixed with alkaline additives improperly, it may affect their promotion activity.

Repeat, the operating environment should also be paid attention to. Although this agent is not highly toxic, it should also avoid long-term inhalation of dust or contact with skin and eyes. In the production site, good ventilation should be ensured, and operators should wear appropriate protective equipment, such as masks, gloves, goggles, etc., to prevent harm to the body.

In short, when using N-tert-butylbenzothiazole-2-sulfinamide, the dosage, temperature, compatibility of additives and operating environment should be treated carefully to ensure the quality of rubber products and the smooth production process.
