Alpha Olefin Sulfonate (AOS) is manufactured by sulfonating
-
alpha-olefins with sulfur trioxide (
) in a falling film reactor, followed by neutralization with sodium hydroxide and hydrolysis to convert sultones into a mix of hydroxyalkane and alkene sulfonates. The process creates a highly biodegradable, anionic surfactant used in shampoos, body washes, and detergents.
Key Stages of AOS Manufacturing:
- Sulfonation: Alpha olefins are reacted with (often diluted with air) in a falling film reactor to create sulfonate intermediates, particularly sultones.

What is the structure of AOS?
The chemical structure of AOS consists of a hydrophilic (water-attracting) sulfonate group attached to a lipophilic (oil-attracting) alkyl chain. This dual nature allows AOS to effectively bridge the gap between water and oil-based substances, making it highly versatile.Sep 29, 2023
