Alpha Olefin Sulfonate (AOS) manufacturing technology involves the continuous sulfonating of

alpha

-olefins (typically

cap C sub 14

cap C sub 16

) using gaseous sulfur trioxide (

cap S cap O sub 3

) in a falling film reactor, followed by neutralization with caustic soda and hydrolysis. The process transforms olefins into a high-foaming anionic surfactant used in personal care and detergent applications.

Sulfonation Process: The core process utilizes a falling film sulfonation reactor where alpha olefins react with gaseous
$cap S cap O sub 3$
, often diluted with nitrogen, to produce sulfonic acids.
Neutralization & Hydrolysis: After aging, the sulfonic acid is neutralized and hydrolyzed using caustic soda (
$cap N a cap O cap H$
), water, and hydrogen peroxide (
$cap H sub 2 cap O sub 2$
) to break down sultones and ensure a stable, high-quality product.
Raw Materials: Alpha olefins are typically derived from ethylene oligomerization (e.g., SHOP process).
Product Forms: The process produces either a 40% liquid solution or a 90% solid bead/powder.
Quality Control: The process must maintain strict control of sultone levels (unsubstituted
, chlorosultones
).
Challenges: The technology is energy-intensive and faces challenges related to high production costs and the need for improved efficiency and environmental sustainability.
