What are the main uses of Sodium Cumene Sulfonate?
Sodium-cumene sulfonate is widely used. In the field of industry, it is often a key ingredient in synthetic detergents. It has good emulsification, dispersion and decontamination capabilities. In detergents, oil stains and other stains can be dispersed in water to achieve the purpose of cleaning. Although there is no exact name for this in the ancient books of Guanfu, it was also explored in ancient times by its decontamination analogy.
Taking the ancient natural decontaminants such as saponin as a guide, sodium-cumene sulfonate has a better decontamination effect. In the textile printing and dyeing industry, it can be used as an auxiliary agent to help the dyes disperse evenly, making the dyeing uniform and good color fastness. In the paper industry, it can also be used as a deinking agent to help remove waste paper inks and recycle fibers for reuse.
Furthermore, in oil extraction, it can be used as an oil displacement agent. In oil reservoirs, crude oil adheres to the rock surface and is not easy to recover. Sodium-cumene sulfonate can reduce the interfacial tension of oil and water, making it easier for crude oil to peel off from the rock surface and improve crude oil recovery.
In daily chemical industry, many detergents, shampoos, body washes and other products contain this ingredient. Because it can effectively clean and is relatively less irritating to the skin, it is widely used. Although there is no such precision in ancient times, today's sodium-cumene sulfonate is an indispensable material for industrial and daily use. It is used in various industries with significant effects and benefits the world.
How safe is Sodium Cumene Sulfonate?
Sodium (Sodium), cumene (Cumene) and sulfonate (Sulfonate) composition, related to safety, must not be ignored.
Sodium, the genus of metals, is extremely active. In contact with water, it reacts rapidly, generating hydrogen and releasing huge heat, even causing ignition. In the air, it is also quickly oxygenated, and the surface changes. It must be protected from water and moisture, and it should be sealed in kerosene or paraffin wax to prevent accidents.
Cumene, an organic compound. Flammable, steam and air mixed, easy to form explosive mixtures. In case of open flame and hot topic, it will explode. And its steam is heavier than air and can spread along the ground, causing ignition at a distant source. If people inhale it, eat it, or touch it on the skin, it is harmful to health, and damages the nervous system, respiratory system and other systems.
Sulfonates have a wide variety of types and different properties. However, some sulfonates may be irritating and corrosive, and can cause discomfort and even damage when they touch the skin and eyes. Some are difficult to degrade in the environment and are tired of ecology.
The three are combined, and the safety concerns are even greater. Sodium is active, and it may react when it encounters impurities in cumene. Cumene is flammable, and sulfonates are oxidizing or explosive.
If you want to use these three, you must know their properties in detail. When handling, strictly follow the rules. Wear protective gear, such as goggles, gloves, protective clothing, etc. In a well-ventilated place, set up fire, explosion-proof, and anti-static measures. When storing, place them according to their properties to avoid heat, moisture, and oxidants. In this way, the security guards are all safe, so that all things can be used properly and avoid disasters.
What are the differences in the application of Sodium Cumene Sulfonate in different industries?
Sodium-cumene sulfonate is used in different industries, and its uses are also different.
In the printing and dyeing industry, this is an excellent auxiliary agent. It can increase the solubility of dyes, promote uniform dyeing of dyes, and make fabrics uniform and bright in color. Its ability to assist in dissolving makes dyes evenly dispersed in the dye solution, without coagulation, and fabric dyeing is more uniform; its ability to promote dyeing can reduce the dyeing rate of dyes, so that dyes are slowly adsorbed on fabrics, achieving the effect of even dyeing.
In the washing industry, it is a key surfactant. It has strong decontamination power, can reduce the surface tension of water, make water more easily penetrate fabric fibers, emulsify and disperse oil stains, and then wash away stains. And rich foam, good stability, help the washing process and improve the washing effect.
In the paper industry, it also has important uses. It can be used as a component of deinking agent to help remove ink from waste paper. By reducing the adhesion between ink and paper fibers, the ink is easier to detach from the paper, and after subsequent treatment, the paper can be recycled.
In the field of chemical synthesis, it can be used as a catalyst or reaction intermediate. The special properties of sulfonate in its structure can participate in some organic synthesis reactions, catalyze specific chemical reaction processes, and help the synthesis of new compounds, providing assistance for the innovative development of the chemical industry. Therefore, sodium-cumene sulfonate has unique functions in various industries, and it shows different values according to industry characteristics and needs.
How is Sodium Cumene Sulfonate produced?
The method of making sodium-based cumene sulfonate is to prepare cumene and place it in a suitable reaction kettle. Sulfuric acid is used as a catalyst to introduce sulfur trioxide, and the two then start a sulfonation reaction. During the reaction, the temperature and reaction time need to be strictly controlled to make the reaction smooth and efficient. After the sulfonation reaction is completed, the cumene sulfonate can be obtained.
Next, the sodium hydroxide is prepared into an appropriate concentration solution and slowly added to the product containing the cumene sulfonate. During this neutralization process, the pH of the solution is carefully adjusted to make the acid and base just to neutralize, and the sodium-based cumene sulfonate solution is obtained.
Then, the solution is separated and purified. First, the excess water is removed by distillation, so that the solution is gradually concentrated. Then filtered to remove insoluble impurities. Then, the crystallization method is used to precipitate sodium-based isopropylbenzene sulfonate from the solution. Finally, by centrifugation or filtration, the pure sodium-based isopropylbenzene sulfonate crystal product is obtained, and then dried to obtain the finished product. This preparation process is interlocked step by step, and each step requires fine operation to obtain high-quality sodium-based isopropylbenzene sulfonate.
What are the advantages of Sodium Cumene Sulfonate compared to other similar products?
Sodium-cumene sulfonate is much better than other imitations.
First, the cleaning ability is quite strong. Sodium-cumene sulfonate has outstanding performance at the active end of the interface, which can greatly reduce the surface tension of water, allowing it to penetrate unimpeded between the stain and the surface of the object, effectively covering and dispersing the stain, and finally achieving the purpose of efficient cleaning. Compared with other products, when removing common stains such as oil stains and sweat stains, it can often achieve better cleaning effect with less dosage, and the cleaning power is better.
Second, the solubility is very good. It dissolves rapidly and uniformly in water, and can form a uniform and stable solution system in a short period of time. This property makes it convenient and fast to dissolve whether it is configured as a liquid detergent or applied to powdered detergents, giving full play to its cleaning effect. In contrast, some similar products may have the disadvantages of slow dissolution and easy agglomeration, compared with the advantages of sodium-cumene sulfonate dissolution.
Third, the chemical properties are stable. Under normal storage and use conditions, sodium-cumene sulfonate can maintain its chemical structure and is not prone to decomposition and deterioration. This stability not only guarantees the shelf life of the product and prolongs its shelf life, but also allows it to maintain relatively consistent performance when used under different environmental conditions, unlike some similar products that are susceptible to temperature, humidity and other factors that cause performance fluctuations.
Fourth, the compatibility is good. Sodium-cumene sulfonate can cooperate with many surfactants, additives and other ingredients to play a synergistic role. In the design of detergent formulations, this good compatibility provides formulators with a broad operating space, allowing them to flexibly prepare products that meet different needs to cope with a variety of cleaning scenarios. Some other similar products may have limitations in compatibility and are difficult to deploy so flexibly.
