2-(morpholinodithio)benzothiazole

2-%28morpholinodithio%29benzothiazole is 2- (morpholine dithio) benzothiazole, which is commonly known as accelerator MDB, is an important rubber vulcanization accelerator. This substance is widely used in the rubber industry, and its main uses are as follows:
First, speed up the vulcanization rate. In the rubber vulcanization process, the addition of accelerator MDB can significantly improve the rate of vulcanization reaction. The vulcanization reaction rate is accelerated, which greatly shortens the production cycle of rubber products, significantly improves production efficiency, and then reduces production costs. This is of great significance for manufacturers of large-scale rubber products. For example, in tire manufacturing, accelerator MDB can quickly vulcanize rubber to meet large-scale production needs.
Second, improve the degree of vulcanization crosslinking. It can promote the formation of more cross-linking bonds between rubber molecules, thereby increasing the cross-linking density of rubber. After the degree of cross-linking is increased, the physical and mechanical properties of rubber products can be improved, such as hardness, tensile strength, wear resistance, etc. are significantly enhanced. For example, the rubber of the conveyor belt can withstand greater tensile force and wear after the action of the accelerator MDB.
Third, optimize the performance of the vulcanized rubber. The accelerator MDB can improve the vulcanization flatness of the vulcanized rubber, that is, within a certain vulcanization temperature range, the rubber properties fluctuate less. In this way, the performance of the rubber products is more stable and uniform, the quality can be improved, and the defective rate is reduced. Like the sealing strip, due to the good vulcanization flatness, the performance of all parts is consistent, and the sealing effect is stable.
Fourth, it has both anti-scorch properties. During the mixing and molding operations in the early stage of rubber processing, the accelerator MDB can prevent the rubber from being vulcanized (scorched) in advance to a certain extent. This provides a larger operating time window for the processing process, ensures the stable performance of the rubber during processing, facilitates subsequent molding operations, and reduces the scrap of the rubber due to scorching.

Its appearance is often light yellow powder and has a special smell. In terms of solubility, it has a certain solubility in organic solvents, such as slightly soluble in organic solvents such as benzene, chloroform, and carbon disulfide, but insoluble in water. This solubility makes it possible to disperse, react or purify it with suitable organic solvents in some organic synthesis reactions or preparation of related products.
In terms of chemical activity, 2- (morpholine dithio) benzothiazole contains atoms with lone pairs of electrons such as sulfur atoms and nitrogen atoms, which make the substance have certain nucleophilicity. Under appropriate conditions, it can react with some electrophilic reagents, such as substitution reactions with halogenated hydrocarbons, to generate new sulfur and nitrogen-containing organic compounds.
The presence of benzothiazole ring in its molecular structure endows the substance with certain stability and conjugation effect. The conjugation system of benzothiazole ring can make the electron cloud distribution more uniform in the molecule, which in turn affects its chemical properties. For example, in some reactions involving electron transfer, benzothiazole ring can play the role of electron transfer or stability reaction intermediate.
In addition, 2- (morpholine dithio) benzothiazole is often used as a vulcanization accelerator in the rubber industry. In the vulcanization process, it can accelerate the reaction between rubber and sulfur, reduce the vulcanization temperature, shorten the vulcanization time, thereby improving the production efficiency of rubber products. And, it can improve the physical and mechanical properties of vulcanized rubber, such as improving the tensile strength and wear resistance of rubber. This is due to its participation in the formation of a suitable cross-linked network structure in the vulcanization reaction.

2-%28morpholinodithio%29benzothiazole that is 2- (morpholine dithio) benzothiazole, often referred to as MBT, its preparation process is as follows:
An appropriate amount of benzothiazole-2-thiol is put into a reactor with stirring, condensation, and dripping device. Morpholine and sodium hydroxide are added in proportion, heated to 60-80 ° C, carbon disulfide is slowly added dropwise under stirring, and the dripping speed is controlled to make the reaction proceed smoothly. After the dripping is completed, the reaction is kept warm for 2-3 hours, and the reaction process is regularly sampled and detected during the period.
After the reaction is completed, the reaction liquid is cooled to room temperature, poured into an appropriate amount of water, the solid is precipitated, filtered, and the filter cake is washed with water several times until the washing liquid is neutral to obtain a crude product. The crude product is put into ethanol, heated to reflux to dissolve, filtered while hot, the filtrate is cooled and crystallized, filtered, and the filter cake is dried at low temperature to obtain 2- (morpholine dithio) benzothiazole of high purity.
During the operation, attention should be paid to the accurate proportion of raw materials, the reaction temperature and time should be strictly controlled, and carbon disulfide is toxic and volatile. The operation should be carried out in a well-ventilated environment, and protective measures should be taken to ensure safe production.

2-%28morpholinodithio%29benzothiazole, it is one of the rubber vulcanization accelerators. When using, many things need to be paid attention to.
bear the brunt of the first, and safety protection must not be ignored. This agent may be harmful to the human body. When exposed, be sure to wear proper protective equipment, such as gloves, goggles, masks, etc., to prevent skin and eyes from coming into contact with it, and to avoid its inhalation. If inadvertently exposed, rinse with plenty of water immediately, and seek medical attention in severe cases.
Furthermore, the dosage also needs to be precisely controlled. If the dosage is too small, the vulcanization promotion effect is not good, and the rubber performance is difficult to achieve expectations; if the dosage is too large, the vulcanization speed may be too fast, and the rubber is easy to scorch, which affects the product quality. Therefore, the dosage needs to be accurately determined according to the type of rubber, vulcanization
Storage is also exquisite. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources, and away from direct sunlight. Due to its active chemical properties, improper storage or deterioration will affect the use effect.
In addition, during use, the mixing process is quite critical. It is necessary to ensure that it is evenly mixed with the rubber, otherwise the concentration of local accelerators will be uneven, which will cause different degrees of vulcanization and affect the performance of the product. Parameters such as mixing temperature and time also need to be strictly controlled.
The compatibility with other additives cannot be ignored. Other additives used in combination with it may have an impact on their promotion effect, so it is necessary to test before use to explore the best combination of additives to achieve the best vulcanization effect and rubber properties.

2-% (morpholinodithio) benzothiazole, that is, 2- (morpholinodithio) benzothiazole, although it does not have its name in "Tiangong Kaiwu", it can be said if it is compared with the same kind in ancient terms.
This substance is used to promote chemical applications such as vulcanization, and its effect is more stable than that of the same kind. If you adjust the tripod, the temperature is stable and the food is delicious. 2- (morpholinodithio) benzothiazole is used for vulcanization, which can make the vulcanization process slow and appropriate, and the physical properties of the finished product are uniform. Take the vulcanization of leather as an example, the same kind or the density of the leather is uneven, but the leather body is tough and smooth, like the good fur of ancient times, light and warm and uniform.
Furthermore, its toxicity is low, and it is safer to use. Ancient creations are also heavy on the word security, and the method of damaging the body is not a good way in the end.
