The product we are discussing is Sodium 2 - ethylhexyl sulfate with the CAS number 126 - 92 - 1. Sodium 2 - ethylhexyl sulfate is an anionic surfactant. Its molecular formula is C₈H₁₇SO₄Na, and its molar mass is approximately 232.27 g/mol.
It usually appears as a white to light - yellow powder or granules. This product is soluble in water and has good emulsifying, dispersing, and wetting properties. It is a common industrial chemical that can be produced on a large scale in factories, ensuring a stable supply at a competitive price.
1. **Detergent Industry**: Sodium 2 - ethylhexyl sulfate is widely used in the formulation of various detergents. It can effectively reduce the surface tension of water, making it easier for detergents to penetrate fabrics and remove dirt and stains. It can be used in laundry detergents, dish - washing liquids, and all - purpose cleaners.
2. **Emulsion Polymerization**: In the field of polymer chemistry, it serves as an emulsifier. During the emulsion polymerization process, it helps to disperse monomers in the water phase, forming stable emulsions. This is crucial for the production of synthetic rubbers, latex paints, and other polymer - based products.
3. **Textile Industry**: It can be used as a wetting agent and dispersant in textile processing. It helps to improve the penetration of dyes and chemicals into the fibers, enhancing the dyeing and finishing effects of textiles.
1. **Detergent Preparation**: When formulating detergents, the appropriate amount of Sodium 2 - ethylhexyl sulfate should be added to the water phase according to the recipe. Usually, the concentration ranges from 5% - 20% depending on the specific requirements of the detergent. Stir well to ensure complete dissolution before adding other ingredients.
2. **Emulsion Polymerization**: In emulsion polymerization, first, prepare an aqueous solution of Sodium 2 - ethylhexyl sulfate with a concentration of about 1% - 5%. Then, add the monomers under stirring conditions. The temperature and stirring speed should be carefully controlled during the reaction to ensure the quality of the polymer emulsion.
3. **Textile Processing**: For textile applications, prepare a working solution with a concentration of 0.5% - 2%. Soak the textiles in the solution for a certain period of time to ensure that the fibers are fully wetted. Then, proceed with the dyeing or finishing process as usual.
1. **Detergent Manufacturer**: A detergent manufacturer added Sodium 2 - ethylhexyl sulfate to their new laundry detergent formula. After market testing, they found that the new detergent had significantly better stain - removal performance compared to the previous formula. The surfactant helped to break down stubborn oil and dirt stains on clothing, and consumers were satisfied with the cleaning results. This led to an increase in the product's market share.
2. **Latex Paint Producer**: A latex paint producer used Sodium 2 - ethylhexyl sulfate as an emulsifier in their paint production. The resulting paint had a more uniform particle size distribution, which improved the paint's gloss and durability. The paint also had better leveling properties, reducing the appearance of streaks and unevenness on the painted surface. As a result, the producer was able to offer a higher - quality product at a competitive price.
3. **Textile Dyeing Factory**: A textile dyeing factory incorporated Sodium 2 - ethylhexyl sulfate in their dyeing process. They noticed that the dyes were more evenly distributed on the fibers, and the color fastness of the dyed fabrics was improved. This reduced the number of defective products and increased the overall efficiency of the dyeing process.
