An Overview of CAS 747-36-4 Manufacturer Insights

Chemical compounds play a crucial role in various industries, ranging from pharmaceuticals to agriculture and beyond. One such compound is CAS 747-36-4, also known as Sodium Dodecylbenzenesulfonate (SDBS). This article provides a comprehensive overview of SDBS, focusing on its manufacturing process, applications, and market trends.

What is Sodium Dodecylbenzenesulfonate?

Sodium Dodecylbenzenesulfonate is an anionic surfactant prominently used in detergents, emulsifiers, and other products that require surface-active agents. It is characterized by its ability to reduce the surface tension of water, making it an invaluable asset in formulations ranging from household cleaning products to industrial applications.

The compound features a hydrophobic dodecyl chain and a hydrophilic sulfonate group, allowing it to interact effectively with both water and oils. This duality is essential for its effectiveness in lifting dirt and grease, making it a favorite in various cleaning applications.

The manufacturing process for Sodium Dodecylbenzenesulfonate typically involves the sulfonation of dodecylbenzene, which is then neutralized with sodium hydroxide. The process can be outlined in several key steps

1. Production of Dodecylbenzene The starting material, dodecylbenzene, is produced through the alkylation of benzene with dodecyl chloride. This reaction requires conditions that promote the formation of a high-purity alkylbenzene product.

2. Sulfonation Reaction The dodecylbenzene is then subjected to sulfonation using oleum or sulfur trioxide. This reaction introduces the sulfonate group (-SO3Na) into the dodecylbenzene structure, which is crucial for its surfactant properties.

3. Neutralization The sulfonated product is treated with sodium hydroxide to achieve the sodium salt form, resulting in Sodium Dodecylbenzenesulfonate. This step is essential to ensure the compound's solubility in water and overall effectiveness in various applications.

4. Purification and Quality Control Following synthesis, the product undergoes purification to remove any unreacted materials and other impurities. Quality control measures, including spectroscopic analysis and surface tension measurement, ensure that the final product meets industry standards.

Applications of SDBS

Sodium Dodecylbenzenesulfonate is widely utilized across several industries. Its primary applications include

- Detergents and Cleaners SDBS is a common ingredient in household and industrial detergents. Its ability to effectively disperse dirt and grease makes it ideal for products ranging from laundry detergents to dishwashing liquids.

- Emulsification The compound is used in emulsion polymerization processes, where it helps stabilize emulsion formulations. It is particularly useful in the manufacture of latex paints and coatings.

- Agricultural Applications In agriculture, SDBS acts as a wetting and dispersing agent in pesticide formulations, enhancing the delivery and effectiveness of these products on crops.

- Personal Care Products The surfactant properties of SDBS are also employed in shampoos, body washes, and other personal care products, contributing to their cleansing and foaming capabilities.

Market Trends

The demand for Sodium Dodecylbenzenesulfonate has been on the rise, largely driven by the increasing need for effective cleaning products in various sectors.
