Sodium Allyl Sulfonate CAS 2495-39-8

Sodium Allyl Sulfonate (SAS) is a new anionic sulfate surfactant. It is easily soluble, dispersible, compatible with hard water, and has high electrolyte stability.Active matter content 95%

Description of Sodium Allyl Sulfonate ：

Sodium allyl sulfonate has excellent wetting, emulsifying, dispersing and permeating properties. It can reduce the surface tension of the water and improve the wettability and permeability of the product, making it easier for the skin to absorb. At the same time, sodium allyl sulfonate also has a certain moisturizing and moisturizing effect, which can improve the phenomenon of dry and rough skin.

In the pesticide industry, sodium allyl sulfonate can be used as a wetting agent, dispersant and penetrant of pesticides to improve the adhesion and permeability of pesticides and increase the effective utilization rate of pesticides. At the same time, sodium allyl sulfonate can also reduce the toxicity of pesticides to the environment and the human body and improve safety.

In addition, sodium allyl sulfonate is used as a wetting agent, emulsifier and dispersant in the cleaning agent industry, which can improve the wettability and permeability of the cleaning solution and enhance the cleaning effect. It is widely used in metal cleaning, textile cleaning and other fields.

Sodium allyl sulfonate is less irritating to the skin and eyes but may still cause skin and eye irritation at high concentrations. Therefore, appropriate safety measures should be taken when using sodium allyl sulfonate. In addition, sodium allyl sulfonate in the production and use of the process may produce waste water and exhaust gas, resulting in a certain impact on the environment. Therefore, effective environmental protection measures should be taken to reduce the discharge of wastewater and gas.

Applications of Sodium Allyl Sulfonate：

The personal care products industry

It can reduce the surface tension of the water and improve the wettability and permeability of the product, making it easier for the skin to absorb. At the same time, sodium allyl sulfonate also has a certain moisturizing and moisturizing effect, which can improve the phenomenon of dry and rough skin.

In shampoos, sodium allyl sulfonate can be combined with other ingredients to produce a rich foam that deeply cleans the scalp and hair, removing dirt and oil. It helps keep hair healthy and makes it softer and smoother. In body washing, sodium allyl sulfonate can play its wetting and emulsifying role, improving the stability of the product and its use effect. It makes the body wash easier to lather and rinse off while keeping the skin moisturized. In facial cleansers, sodium allyl sulfonate helps to improve the product's cleansing effect and skin affinity.

Pesticide industry

Sodium allyl sulfonate is used in the pesticide industry as a pesticide-wetting agent, dispersant, and penetrant. It can improve the adhesion and penetration of pesticides and enhance their control effect. Using sodium allyl sulfonate as a pesticide additive can reduce the amount and frequency of pesticides and reduce environmental pollution.

In pesticide formulation, sodium allyl sulfonate can promote the adhesion of pesticides on plant leaves and improve the utilization rate of pesticides. It can also help pesticides penetrate better into the plant and promote the effective delivery of pesticides. This helps to improve the control effect of pesticides, reduce the loss and waste of pesticides, and reduce the impact on non-target organisms.

In addition, sodium allyl sulfonate can also be used with other pesticide additives, such as wetting agents, dispersants and stabilizers, to enhance the performance and effect of pesticides further. These combinations can improve pesticides' solubility, dispersion, and stability to maintain good performance under various environments and conditions.

Cleaning agent industry

Sodium allyl sulfonate is widely used in the cleaning agent industry in industrial cleaning, textile cleaning and other fields. It can improve the wettability and decontamination ability of the cleaning solution and help the cleaning agent better remove various dirt and residues.

In industrial cleaning, sodium allyl sulfonate can be used as a wetting agent and emulsifier, widely used in metal, glass, plastic, and other hard surface cleaning. It can improve the wettability and decontamination ability of the cleaning solution and help the cleaning agent better penetrate and remove various dirt. This helps keep the material clean and glossy, extending its service life. In textile cleaning, sodium allyl sulfonate can play its wetting and emulsifying role, which helps to improve the washing effect of the cleaning solution. It separates the stain from the fabric, making it cleaner and softer after washing. This helps to improve washing efficiency, reduce water consumption, and reduce environmental pollution.

Production Method of Sodium Allyl Sulfonate：

Direct sulfonation

Direct sulfonation is a common method to produce sodium allyl sulfonate. Sodium allyl sulfonate was synthesized by sulfonation from allyl alcohol and concentrated sulfuric acid. In the reaction process, concentrated sulfuric acid is used as a sulfonation agent to sulfonate with allyl alcohol to produce the corresponding sulfonate. Then, the sulfonate is converted into salt compounds by a neutralization reaction, and finally, the allyl sulfonate product is obtained by salting out crystallization.

The advantages of direct sulfonation are that the process is mature, raw materials are readily available, and the price is relatively low. To reduce the discharge of wastewater and exhaust gases, it is usually necessary to use recycling cooling, absorption or incineration methods for treatment.

REDOX method

The REDOX process is another method for producing sodium allyl sulfonate. Using allyl ether as the main raw material, the corresponding sulfonate was produced by the REDOX reaction, and then the allyl sulfonate product was obtained by neutralization. In the REDOX reaction, oxidizing agents such as hydrogen peroxide or persulfate usually oxidize allyl ether to the corresponding alcohol and then reduce it with sulfur dioxide to produce sulfonate.

The advantage of the REDOX method is that the discharge of wastewater and waste gas is less, and the pollution to the environment is less. In addition, the method can also control the quality and performance of the product by adjusting the ratio of raw materials and reaction conditions. However, the drawback of the REDOX method is that the raw material cost is higher, and the need to use more organic solvents increases the production cost and environmental protection burden.

In addition to the two common methods above, other methods, such as transesterification, etherification, etc., can also produce sodium allyl sulfonate. These methods have advantages and disadvantages in the actual production can be based on raw material sources, equipment investment, production costs, environmental protection requirements, and other factors to choose the appropriate production method.

Select the right catalyst: In some methods, a catalyst is needed to facilitate the reaction. Choosing the appropriate catalyst can improve the reaction rate and yield and reduce the formation of by-products.

Recycling: Some raw materials and solvents can be recycled to reduce production costs and environmental pollution.

Environmental protection treatment: The wastewater and waste gas generated in the production process must be treated to reduce environmental pollution. It can be treated by physical treatment, chemical treatment and biological treatment.
