Linear Alkyl Benzene Sulfonic Acid

Product: Linear Alkyl Benzene Sulfonic Acid (LABSA)

Chemical Formula: C18H30O3S

Linear Alkyl Benzene Sulfonic Acid (LABSA) is an organic compound used primarily as a surfactant in various industries. Here are five important points about LABSA:

1. Chemical Composition: LABSA is an anionic surfactant consisting of a linear alkyl chain attached to a benzene ring, with a sulfonic acid group (-SO3H) as the functional group. Its chemical formula is C18H30O3S.

2. Physical Properties: LABSA is a brown viscous liquid with a characteristic odor. It is soluble in water and various organic solvents. LABSA has excellent wetting, foaming, and emulsifying properties, making it suitable for use as a surfactant.

3. Production: LABSA is produced by sulfonating linear alkyl benzene (LAB) with sulfuric acid. The reaction between LAB and sulfuric acid introduces the sulfonic acid group (-SO3H) onto the benzene ring, resulting in the formation of LABSA.

4. Surfactant Properties: LABSA is an effective surfactant due to its amphiphilic nature. It has both hydrophilic (water-loving) and hydrophobic (water-repelling) regions, enabling it to lower surface tension, promote dispersion, and enhance the cleaning and foaming properties of various products.

5. Biodegradability: LABSA is biodegradable, which means it can be broken down by microorganisms present in the environment. This property makes it a preferred choice in industries where environmental sustainability is a concern.
