The method of preparing 2-benzothiazole sulfinic acid is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced from the relevant chemical principles and common preparation methods.
To prepare 2-benzothiazole sulfinic acid, the common starting material is 2-mercaptobenzothiazole. The method is as follows:
Take an appropriate amount of 2-mercaptobenzothiazole and place it in the reaction vessel. Dissolve in a suitable solvent, which needs to have good solubility and stable properties to the reactants, such as ethanol, dichloromethane, etc. After
, slowly add a suitable oxidizing agent. Common oxidizing agents such as hydrogen peroxide, m-chloroperoxybenzoic acid, etc. When adding an oxidizing agent, it is advisable to control the temperature and drip rate. If the temperature is too high, the reaction may be too violent, causing the product to decompose or form by-products; if the drip rate is too fast, it also has this disadvantage. Usually, the temperature can be controlled at 0-30 ° C, and the oxidizing agent is slowly added to make the reaction proceed smoothly.
During the reaction process, the reaction process can be monitored by thin-layer chromatography (TLC) or other analytical methods. When the reaction reaches the desired level, that is, the reaction raw materials are exhausted or the amount of product generation does not increase, the reaction is terminated.
After the reaction is terminated, the reaction mixture is treated. If there is insoluble matter in the reaction, it can be filtered and removed first. After that, the product can If column chromatography is used, appropriate silica gel is selected as the stationary phase, eluted with different proportions of eluent, and the fractions containing the target product are collected. After vacuum distillation, recrystallization, etc., pure 2-benzothiazole sulfinic acid can be obtained.
It should be noted that the whole preparation process should be carried out in a well-ventilated environment, and follow the safety procedures of chemical experiments to avoid danger.

2-Benzothiazole sulfinic acid is a very important chemical substance. During use, many precautions must be paid attention to.
First, the way of protection should not be ignored. This substance may be harmful to the human body. When exposed, be sure to wear appropriate protective equipment. If you wear protective gloves to prevent it from coming into direct contact with the skin, causing skin irritation or even corrosion. You also need to wear protective goggles. If accidentally splashed into the eyes, it can cause serious eye damage. Masks are also indispensable because their volatile gaseous substances may irritate the respiratory tract, cause excessive inhalation, or cause cough, asthma and other discomfort.
Second, storage methods are also crucial. It should be stored in a cool, dry and well-ventilated place. Keep away from fire and heat sources, because of its certain chemical activity, high temperature environment or damage to its stability, causing dangerous chemical reactions. And it needs to be stored separately from oxidants, alkalis and other substances, because of its active chemical properties, mixed with other substances, or react violently, endangering safety.
Third, when using, the operating specifications must be strictly observed. Perform relevant operations in the fume hood to ensure air circulation and disperse possible harmful gases in time. Use an appropriate amount and do not use it in excess to avoid unnecessary waste and danger. After operation, the utensils used should be cleaned in time, properly dispose of the remaining substances, and do not dump them at will to prevent environmental pollution.
Fourth, the emergency treatment strategy must be well known. If you accidentally come into contact with the skin, you should immediately rinse with a large amount of flowing water, and then seek medical treatment. If you splash into the eyes, quickly rinse with a large amount of water, lift the eyelids, and continue to rinse for several minutes. You also need to seek medical attention as soon as possible. If you inhale, quickly move to a fresh air place to keep the respiratory tract unobstructed. If you have breathing difficulties, give oxygen, and if necessary, perform artificial respiration and seek medical attention.
