Mesitylene-2-Sulfonic Acid Chloride is synthesized
The method of preparing trimethylbenzene-2-sulfonic acid acid chloride is generally as follows.
Often trimethylbenzene is used as the starting material, and after the step of sulfonation, trimethylbenzene-2-sulfonic acid is obtained. When sulfonating, sulfuric acid, fuming sulfuric acid, etc. are selected as sulfonating agents. If sulfuric acid is used, the concentration, dosage, reaction temperature and time are all critical. If the temperature is high, the reaction speed will increase, but the side reactions will also increase; if the temperature is low, the reaction will be slow and take a long time. Generally, when the temperature is controlled in a moderate range, such as 80-120 degrees Celsius, the reaction number can be effectively converted into trimethylbenzene-2-sulfonic acid.
After obtaining xylene-2-sulfonic acid, it is chlorinated to form xylene-2-sulfonic acid chloride. Commonly used chlorinating agents are phosphorus pentachloride, dichlorosulfoxide, etc. Taking dichlorosulfoxide as an example, it reacts with xylene-2-sulfonic acid, and in addition to generating the target xylene-2-sulfonic acid chloride, by-product sulfur dioxide and hydrogen chloride. This reaction is usually carried out in organic solvents, such as toluene, dichloromethane, etc. The solvent can help the reactants to disperse and the reaction can occur uniformly. The reaction temperature also needs to be considered, generally at 40-80 degrees Celsius. The reaction lasts for several hours until no gas escapes, which can be regarded as the end of the reaction. After the reaction is completed, the pure trimethylbenzene-2-sulfonyl chloride can be obtained by distillation, filtration, recrystallization and other purification techniques.
In this way, according to the order of sulfonation, chlorination and purification, trimethylbenzene-2-sulfonyl chloride can be prepared.
Mesitylene-2-Sulfonic Acid Chloride during storage and transportation
In the case of chlorine sulfonate, various precautions should be taken during storage and transportation. This is a chemically active substance and must be treated with care.
When storing, the first environment. It must be placed in a cool, dry and well-ventilated place. Because if the substance is in a high temperature and humid place, it may cause chemical mutation and cause danger. High temperature can promote its reaction to intensify, and humid gas may cause it to hydrolyze, damage its quality, and even cause safety risks.
Furthermore, the storage place must be kept away from fire and heat sources. Chlorine sulfonate may be flammable, and it may cause combustion or even explosion in case of open fire, hot topic, or cause disaster. Therefore, in the warehouse, fireworks are strictly prohibited, and electrical equipment should also comply with explosion-proof regulations.
In addition, it should be stored in isolation from oxidants, alkalis, etc. This is because of its active chemical properties, mixed with oxidants, or severe oxidation reaction; when it encounters alkalis, it is easy to cause reactions such as neutralization, which can cause dangerous accidents.
When transporting, the packaging must be tight. Choose packaging materials suitable for this material to ensure that there is no leakage during transportation. And the transportation vehicle should also be clean, dry, and have no residues that can react with it.
Transportation personnel must undergo professional training, familiar with their chemical characteristics and emergency treatment methods. Driving on the way, driving slowly, absorbing shocks and collisions. In case of accidental leakage, it should be handled immediately according to the plan to evacuate the crowd, prevent the spread of pollution, and ensure the safety of personnel and the environment. In this way, the chlorine myrsulfonate must be properly stored and transported to avoid accidents.
Mesitylene-2-Sulfonic the market price of Acid Chloride
The price of all kinds of goods varies according to many reasons, such as the state of supply and demand, the cost of materials, and the difficulty of production, and the current situation also has an impact. Now I want to know the market price of mesitylene-2-sulfonyl chloride, but this is not an easy matter.
Cover trimethylbenzene-2-sulfonyl chloride, which is used in the field of chemical industry, is quite specialized. The needs of the market may be tied to the needs of specific industries, such as fine chemical preparations, special material preparation, etc. If such industries are booming and there are many people seeking it, the price may increase; conversely, if the related industries are sluggish, the demand is less and the supply is more, and the price will drop.
The source of its materials and the method of production are also related to cost and price. The production of trimethylbenzene-2-sulfonyl chloride requires specific raw materials. If the price of raw materials fluctuates, the price of its finished products is also difficult to stabilize. And if the production process is difficult, labor and material resources are required, and the price is also high; if the process is advanced and the cost is controlled, the price may be close to the people.
In addition to the situation of the world and the rules of trade, it also affects the price. If there is a trade dispute, the tariff increases, or the transportation is blocked, the cost of its circulation will increase greatly, and the price will also rise.
However, after checking the records of the past years, the exact price of trimethylbenzene-2-sulfonyl chloride has not been obtained. However, based on common sense, it is a fine chemical, and the production may be difficult, and the raw materials may be exquisite. If it is in the ordinary market, in terms of kilograms, its price may be between hundreds and thousands of yuan. However, this is only an estimate, and the actual price should be based on the current business conditions in the chemical market and the quotations of each supplier. To obtain an accurate price, you need to consult the trading house of chemical materials and the franchisee before you can know the details.
