Frequently Asked Questions
What is the use of Meta-Nitro Benzene Sulfonic Acid-Sodium Salt?
Sodium nitrobenzene sulfonate is widely used in the printing and dyeing industry. First, it can be used as a dye preventative when dyeing vat dyes. In the dyeing process of vat dyes, fabrics occasionally come into contact with air, and some dyes are easily oxidized, resulting in uneven dyeing. Sodium nitrobenzene sulfonate has oxidative properties and can reduce the oxidized dyes again to ensure uniform dyeing and pure color.
Second, it is also an important auxiliary in the printing process. Adding this substance to the printing paste can prevent the printing fabric from being stained on the white ground. Because it can inhibit the excessive reduction of reducing agents in the paste, avoid the reduction products from being stained on the white ground, and maintain the clear and white printing pattern.
Furthermore, in the field of dye synthesis, sodium nitrobenzene sulfonate also plays a key role. It often participates in the synthesis reaction of some dye intermediates as a mild oxidizer, helping to adjust the reaction process and product structure, improve the efficiency and quality of dye synthesis, and then meet different dyeing and printing needs, so that the printing and dyeing products are rich in color and high quality.
What are the physicochemical properties of Meta-Nitro Benzene Sulfonic Acid-Sodium Salt
Meta - Nitro + Benzene + Sulfonic + Acid - Sodium Salt, that is, sodium m-nitrobenzene sulfonate, is a kind of organic compound. Its physical properties are quite remarkable.
Looking at its morphology, it often shows a white crystalline powder, which is easy to identify and operate. Its solubility is also characteristic, it can be soluble in water, and can be dispersed evenly in water to form a uniform system.
When it comes to melting point, sodium m-nitrobenzene sulfonate has a high melting point, which makes it stable in solid state within a certain temperature range, providing convenience for related industrial operation and storage.
Furthermore, the hygroscopicity of sodium m-nitrobenzene sulfonate should not be underestimated. In high humidity environments, it is easy to absorb moisture in the air. Therefore, it is necessary to pay attention to moisture-proof during storage to maintain its quality and performance.
Its aqueous solution is neutral, and this chemical property is of great significance in many chemical reactions and industrial applications. It can provide a specific acid-base environment for the reaction, which affects the reaction process and product generation.
The above physical properties have important application value in many fields such as chemical industry, printing and dyeing, and play a key role in industrial production and scientific research.
What is the production method of Meta-Nitro Benzene Sulfonic Acid-Sodium Salt?
The method of making sodium m-nitrobenzene sulfonate used to start with benzene. First, benzene is co-heated with sulfuric acid to carry out a sulfonation reaction. Sulfuric acid has strong sulfonation ability. In this reaction, the sulfonic acid group of sulfuric acid (-SO 🥰 H) replaces the hydrogen atom on the benzene ring, and then benzene sulfonic acid is obtained.
Subsequently, benzene sulfonic acid is co-disposed with concentrated nitric acid and mixed acid of concentrated sulfuric acid to carry out a nitrification reaction. Nitric acid is catalyzed by concentrated sulfuric acid to form nitrosyl positive ions (NO 🥰), which have strong electrophilicity and can attack specific positions of the benzene ring in the benzene sulfonic acid molecule. The sulfonic acid group of benzene sulfonic acid is the meta-locator, so the nitrosyl positive ions mainly attack the
Finally, a base (such as sodium hydroxide) interacts with m-nitrobenzene sulfonic acid, and the hydrogen atom of the sulfonic acid group is replaced by sodium ions, resulting in sodium m-nitrobenzene sulfonic acid.
There are other ways to prepare it. Or first react with benzene and nitric acid to obtain nitrobenzene, and then sulfonate, or obtain m-nitrobenzene sulfonic acid, and then prepare m-nitrobenzene sulfonic acid. However, the method of sulfonation and then nitrification is more commonly used, because its yield and selectivity are more advantageous in actual production.
Meta-Nitro Benzene Sulfonic Acid-Sodium Salt requires attention during storage and transportation
Sodium nitrobenzene sulfonate, during storage and transportation, many key matters need to be paid attention to.
Its properties have specific chemical activities and are prone to changes when heated. When storing, first choose a cool, dry and well-ventilated place.

This salt dissolves in water, or causes water quality to deteriorate, affecting the habitat of aquatic organisms. If this salt is contained in water, it may change the chemical properties of the water body, such as pH, electrical conductivity, etc. And it may be a substrate for microbial metabolism, and the metabolic process may generate other harmful by-products, further polluting the water body. If this contaminated water is used for irrigation, it will also harm the soil, cause soil chemical properties to change, affect soil fertility and structure, and in the long run, may hinder the growth of vegetation, causing damage to the regional ecological balance.
As for the human body, sodium nitrobenzene sulfonate may be latent risk. It may invade the human body through breathing, skin contact or ingestion. Inhalation of dust containing this salt, or irritation of the respiratory tract, causing cough, asthma and other discomfort, long-term exposure, more likely to damage lung function. Skin contact, or cause allergies, inflammation and other reactions, because it may interfere with the normal physiological functions of the skin. If accidentally ingested, digested and absorbed in the body, or affect the function of organs, such as liver, kidney and other detoxification and excretion organs, because of its chemical composition or interference with the normal biochemical reactions of the human body, long-term accumulation, or increase the risk of disease.
In summary, sodium nitrobenzene sulfonate has a significant impact on the environment and human body, so its production, use and disposal should be treated with caution to prevent damage to the environment and human body.
