Sodium sulfonate (Sulfonate) is a class of compounds with the structure of sulfonic acid group (-SO
) bound to sodium ion (Na
If it is sodium m-trimethylbenzene sulfonate, its chemical structure is based on the benzene ring of m-trimethylbenzene. After one hydrogen atom is replaced by a sulfonic acid group (-SO < H), it forms a salt with sodium ions. In this structure, the benzene ring retains its aromaticity, and the three methyl groups remain in the meso position, while the sulfonic acid group forms an ionic bond with the sodium ion.
Sodium m-trimethylbenzenesulfonate is often used as a surfactant because it contains hydrophilic sulfonic acid groups, lipophilic benzene rings and methyl groups, and is used in many fields of industry and daily life. For example, in detergents, it can reduce surface tension and enhance decontamination performance; in some chemical reactions, it can also act as a catalyst or auxiliary to assist the reaction.
In this way, the chemical structure of sodium m-trimethylbenzenesulfonate fuses the characteristics of aromatic hydrocarbons and sulfonates, resulting in unique physical and chemical properties and application value.

Sodium metamethylbenzene sulfonate has an amphiphilic structure, one end is hydrophilic and the other end is hydrophilic, which can effectively reduce the surface tension of water, enhance the emulsification, dispersion and solubilization ability of detergent to oil stains, make the washing effect better, and can quickly remove all kinds of stubborn oil stains and stains.
In the paint industry, it also has significant uses. It can be used as a coating additive to improve the leveling and wettability of coatings, promote the uniform spread of coatings on the surface of the coated object, avoid undesirable phenomena such as hanging and orange peel, and greatly improve the film-forming quality and appearance effect of coatings.
In the field of petroleum exploration, it can be used to prepare oil displacement agents. By reducing the interfacial tension between oil and water, the recovery rate of crude oil is improved, which helps to extract oil resources more efficiently and increase oil production.
In addition, in some chemical reactions, sodium meta-toluene sulfonate can also act as a catalyst or reaction medium, which affects the process and rate of the reaction, and helps to synthesize many specific organic compounds, providing strong support for the development of organic synthesis chemistry.
What are the precautions in the use of Mesitylene Sodium Sulfonate?
When using mesitylene and sodium sulfonate, there are many things to pay attention to. The first priority is safety, both of which have certain chemical activity. Mesitylene is a flammable liquid, and its vapor and air can form an explosive mixture, which can cause combustion and explosion in case of open fire and high heat. Therefore, the site of use must be kept away from fire and heat sources, well ventilated, and should be equipped with suitable fire-fighting equipment.
Furthermore, although the chemical properties of sodium sulfonate are relatively stable, some sodium sulfonate may cause irritation if it comes into contact with the skin or eyes. Wear appropriate protective equipment, such as protective gloves, goggles, etc. during operation to prevent accidental contact. In case of accidental contact, rinse with plenty of water immediately and seek medical attention as appropriate.
In the chemical reaction process, the ratio of the two, the reaction temperature, the reaction time and other conditions all have a significant impact on the reaction result. It must be precisely adjusted according to the specific reaction requirements to achieve the expected reaction effect. For example, the reaction temperature is too high, or the side reactions increase; improper ratio, or the product purity is poor.
In addition, the separation and purification of the product after the reaction also need to be treated with caution. Because the reaction system or contains impurities such as unreacted raw materials and by-products, suitable separation methods, such as distillation, extraction, crystallization, etc. should be selected to obtain high-purity products.
During the operation, environmental protection should also be paid attention to. If any waste is generated, it needs to be properly disposed of in accordance with relevant regulations, and it must not be discharged at will to avoid polluting the environment. Overall, when using trimethylbenzene and sodium sulfonate, it is necessary to operate with caution, paying attention to safety, reaction conditions, product handling, and environmental protection in order to ensure the smooth progress of the experiment or production.
What is the preparation method of Mesitylene Sodium Sulfonate?
The preparation of sodium mesitylene sulfonate requires following certain chemical procedures. First, the starting material is mesitylene, which is an aromatic hydrocarbon with a special structure. Under suitable reaction conditions, the sulfonation reaction of mesitylene with a sulfonating agent occurs. Commonly used sulfonating agents, such as concentrated sulfuric acid or fuming sulfuric acid.
During the reaction, the reaction temperature, time and the proportion of reactants need to be precisely controlled. If the temperature is too high, it may cause more side reactions and affect the purity of the product; if the temperature is too low, the reaction rate will be slow and take a long time. Generally speaking, this sulfonation reaction is suitable for a certain temperature range, such as between [X] ° C and [X] ° C.
When the mesitylene is fully reacted with the sulfonating agent, a product containing mesitylene sulfonic acid is obtained. At this time, it needs to be further converted into sodium mesitylene sulfonate. Neutralization can be used to select suitable alkaline substances, such as sodium hydroxide, and slowly add them to the reaction system. During the neutralization process, attention should also be paid to controlling the reaction conditions to ensure that the reaction proceeds smoothly and avoid local overheating or overalkali conditions to prevent damage to the product.
After the neutralization reaction, the solution contains sodium mesitylene sulfonate. Subsequent steps need to be separated and purified to obtain high-purity products. Operations such as crystallization, filtration, and washing can be used to remove impurities, so that sodium mesitylene sulfonate can be precipitated in a pure form. In this way, the product of sodium trimethylbenzenesulfonate that meets the requirements can be obtained. The whole preparation process requires rigorous operation and attention to detail to achieve the ideal preparation effect.
What is the market price range for Mesitylene Sodium Sulfonate?
Alas! To know the market price range of mesitylene and sodium sulfonate is a matter of great concern to the industry. However, its price often varies due to factors such as time, place, quality and supply and demand, and it is difficult to determine a certain number.
In the past, the price of mesitylene may vary due to the abundance of raw materials and the complexity and simplicity of the process. If the raw materials are abundant and the process is advanced, the price may become stable and cheap; conversely, if the raw materials are scarce and the process is difficult, the price may rise. In different seasons, or due to the lack of market demand, the price also fluctuates. In peak season, when demand exceeds supply, the price will rise; in off-season, when supply exceeds demand, the price may fall. In the past few years, the price of sodium sulfonate fluctuated every time, or hovering between [X1] yuan/ton and [X2] yuan/ton.
As for sodium sulfonate, its price is also influenced by a variety of reasons. The cost of production, such as the price of raw materials, energy consumption, manpower, etc., are all key. And different categories and purity of sodium sulfonate, the price is also different. High purity, the price must be higher than ordinary ones. Market competition also affects its price. Many companies compete in the market, or adjust prices for profit. In the past, the price of sodium sulfonate often fluctuated between [Y1] yuan/ton and [Y2] yuan/ton.
Overall, in order to determine the current accurate market price range of the two, it is also necessary to carefully investigate the current market situation, consult the industry's brokers, brokers, or obtain recent prices.
