Sodium-based straight-chain α-olefin sulfonates have a wide range of uses and are useful in many fields.
In the field of daily chemical industry, this is an important surfactant. In detergents, its decontamination power is strong, and it can effectively remove all kinds of oil stains and stains. Because of its good emulsification, dispersion and solubilization properties, it can make oil and fat substances evenly dispersed in water, so as to achieve the effect of cleaning. And the material has good biodegradability and is environmentally friendly, so it is widely used in household washing powder, detergent and other products.
In the field of industrial cleaning, it is also indispensable. Such as metal processing cleaning, it can remove oil stains on metal surfaces, cutting fluid residues, etc., to ensure that the metal surface is clean and conducive to subsequent processing processes. In the textile printing and dyeing industry, it can be used as a scouring agent, a desizing agent, to remove natural impurities, slurries, etc. on fabrics, and improve the whiteness and wettability of fabrics.
In the field of petroleum exploration, it can be used as an oil displacement agent. Due to its surface activity characteristics, it can reduce the interfacial tension of oil and water, make crude oil easier to be displaced from rock pores, and improve crude oil recovery. It can improve the oil-water fluidity ratio, expand the spread volume, and then improve the efficiency of oil field production.
In agriculture, it can be used as a pesticide auxiliary agent. It helps pesticides to be evenly dispersed on the surface of crops, enhances the adhesion and permeability of pesticides, improves the efficacy of pesticides, reduces the amount of pesticides, and reduces the impact on the environment.
In the field of emulsion polymerization, it can act as an emulsifier. The monomer is uniformly dispersed in the aqueous phase to form a stable emulsion system, which is convenient for the polymerization reaction. It is of great significance for the synthesis of various polymer, such as synthetic rubber and synthetic resin.

Sodium-based straight-chain α-olefin sulfonates have various specific properties. Its mild nature, just like the soft wind in spring, is less irritating to the skin and hair, and can care for the human body. Therefore, it is often used in personal care products, such as cleansers, shampoos, etc., to make people feel soft and comfortable.
In addition, its solubility is good, whether cold water or hot water, it can be instantly dissolved, just like fish entering water, free and unhindered. This characteristic makes it very convenient when blending a variety of formulas, and can be evenly mixed with others.
And it has strong decontamination power, like a warrior to kill the enemy, it can quickly remove oil and dust. Clothes are washed by it, clean and renewed, and it is important in detergents.
It also has good biodegradability. In the natural environment, such as fallen leaves returning to their roots, it can gradually decompose into harmless things, which are environmentally friendly and in line with the current trend of environmental protection.
Its foam performance is also excellent, and it can produce rich and fine foam, such as a dream cloud, which increases the sense of pleasure in use, and the foam stability is good, which can continue to play a role in the cleaning room.
In addition, it has strong compatibility and can be integrated with many surfactants, additives, etc., synergistic, such as combining the phase and making the country strong, expanding its application scope, and shining in the fields of industrial and civil cleaning.

The production process of sodium-based straight-chain α-olefin sulfonates is not directly described in ancient books, but it can be understood in terms of chemical theory.
The first step is the sulfonation of olefins. Choose a suitable straight-chain α-olefin, often in the gas or liquid phase, and encounter sulfonating agents. Sulfonating agents are mostly sulfur trioxide. When the two meet, they are controlled according to precise temperature and pressure in a special reactor. If the temperature is high, side reactions will occur and the product will be impure; if the temperature is low, the reaction will be slow and inefficient. Therefore, the temperature is often stable in a moderate range, and the pressure is also adapted to it. It promotes the quick combination of olefins and sulfur trioxide, and the intermediate of olefin sulfonic acid.
The second is the process of neutralization. After obtaining olefin sulfonic acid, neutralize it with alkali solution such as sodium hydroxide. This step requires careful adjustment of pH to make the system nearly neutral. The amount of alkali and the speed of addition are all key. If the amount is small, the sulfonic acid will not be fully neutralized. If the amount is large, the product will be too alkaline, which will damage the quality of the product.
Then it is hydrolyzed. Some sulfonolactones need to be hydrolyzed to form hydroxyalkyl sulfonates to improve the product composition. When hydrolyzing, the water temperature, duration, and the presence or absence of catalysts need to be investigated in detail. If the water temperature is too high, the product may decompose; if the water temperature is too low, the hydrolysis will be difficult. The duration also needs to be precisely controlled. If it is too long, it
The end is the order of refining. After the reaction is completed, the product may contain impurities, which need to be separated and purified. By filtering to remove solid impurities, distillation, extraction, etc. to remove liquid impurities, the purity of sodium-based straight-chain α-olefin sulfonate rises, reaching the standards used in various industries.
This series of processes are interconnected, and the loss of any link will lead to changes in product quality. The wonders of chemical industry can be seen here. We must control it with a rigorous state and scientific method to obtain high-quality sodium-based straight-chain α-olefin sulfonate.

Sodium-based straight-chain α-olefin sulfonate (Sodium Linear Alpha Olefin Sulfonate) has many advantages over other similar products.
First of all, in terms of decontamination ability, this product is excellent. Its molecular structure is unique, and the straight-chain characteristics enable it to penetrate into the dirt more efficiently when in contact with stains. With the strong hydrophilicity of the sulfonic acid group and the affinity of oil stains, the stubborn oil stains are peeled off from the surface of fabrics or objects and dispersed in water, and the decontamination effect is far better than that of the same kind. The ancients said: "If you want to do something well, you must first use its tools." When it comes to cleaning, sodium-based straight-chain α-olefin sulfonate is that sharp tool, which can quickly disintegrate stains and make cleaning twice as effective.
Furthermore, its biodegradability is very good. In today's era of environmental protection, this characteristic is crucial. In the natural environment, it can be quickly decomposed by microorganisms and turned into harmless things. Unlike some congeneric products, it remains in the environment and becomes a source of pollution. This is just as the Book of Changes says: "My husband is in harmony with heaven and earth, and with the sun and the moon." Sodium-based linear α-olefin sulfonate is integrated with the natural environment, follows the laws of nature, and does not disturb ecological harmony.
In addition, it is less irritating. Whether it is used for fabric washing or cleaning products that come into frequent contact with the human body, they have minimal irritation to the skin and mucous membranes, greatly ensuring the comfort and health of the user. Like a gentle spring breeze, it passes by without any harm. Many similar products may cause skin discomfort due to ingredient problems, while sodium-based straight-chain alpha-olefin sulfonates have no such danger, creating a safe cleaning experience for users.

Sodium Linear Alpha Olefin Sulfonate (LAS) has a significant impact on the environment.
LAS is a commonly used anionic surfactant, which is widely used in detergents, detergents and other products. Its impact on the environment has positive and negative ends.
First of all, it is negative. If LAS is discharged into the water body in large quantities, it is easy to cause eutrophication of the water body. Because it contains elements such as sulfur and carbon, it can be a nutrient for microorganisms and promote the excessive reproduction of aquatic organisms such as algae. After algae grow crazy, it may reduce the dissolved oxygen in the water, endangering the survival of aquatic animals such as fish. And LAS itself may be toxic to aquatic organisms, affecting their growth, reproduction and behavior. Such as causing damage to the gill tissue of fish, interfering with its respiration; affecting the plankton, or affecting its population structure and quantity, disrupting the balance of aquatic ecosystems. And it accumulates in the soil, or affects the physical and chemical properties and microbial activities of the soil, hinders the absorption of nutrients and water by plant roots, and affects plant growth.
However, it also has a positive effect. LAS has relatively good biodegradability. In a suitable environment, it can be decomposed by microorganisms into harmless small molecules, reducing the risk of long-term pollution. And because of its efficient cleaning ability, it can be used rationally in detergents, which can reduce the amount of detergent and indirectly reduce the resource consumption and environmental pollution caused by the production of large amounts of detergents.
In short, LAS has a complex impact on the environment. When products containing LAS are used rationally and properly, they can reduce their negative effects, promote their positive effects, and maintain the balance of the environment and ecology.
