Sodium bisulfite (CAS No. 2682-20-4) - Properties, Uses, and Safety

Understanding CAS No. 2682-20-4 A Comprehensive Overview

CAS No. 2682-20-4 refers to a specific chemical compound known as Dodecylbenzenesulfonic acid (DBSA). This compound belongs to a class of chemicals known as alkylbenzenesulfonic acids, widely used in various industrial applications. Understanding DBSA and its properties is essential for industries that utilize it in formulations and products.

Chemical Properties and Structure

Dodecylbenzenesulfonic acid is characterized by its long hydrophobic alkyl chain attached to a benzene ring, which is further connected to a sulfonic acid group. The chemical formula of DBSA is C18H30O3S, indicating its complex structure that contributes to its unique physical and chemical properties. It is a viscous liquid at room temperature and is typically light yellow to amber in color.

Applications in Industry

DBSA has a wide array of applications, particularly in the formulation of surfactants, detergents, and emulsifiers. Due to its strong surfactant properties, it is commonly used in household cleaning products and industrial cleaners. Its ability to lower surface tension makes it effective in enhancing the solubility of other compounds and improving the cleaning action of detergents.

Furthermore, DBSA is utilized in the production of lubricating oils, where its properties help to reduce friction and wear. It acts as an effective dispersant and can enhance the stability of emulsions, making it valuable in industries such as automotive and manufacturing.
