AI Overview
Alpha Olefin Sulfonate (AOS) hydrolysis is a critical step in producing high-quality surfactants, where sulfonated alpha-olefins (sultones) are converted into hydroxyalkane sulfonates and alkene sulfonates. It typically occurs at
for about
minutes in a continuous process, yielding over
of the surfactant product.
Key Aspects of AOS Hydrolysis:
- Purpose: The process converts sultones—formed during the sulfonation of -olefins—into usable surfactants, reducing raw material odor and improving foaming properties.
- Process Conditions: The reaction involves neutralizing the sulfonated product with agents like sodium hydroxide, followed by high-temperature, high-pressure hydrolysis, often in a specialized hydrolyzer.
- Components: The hydrolyzed product typically contains alkenyl sulfonate andhydroxyalkane sulfonate.
- Optimized Method: Modern production often uses a continuous flow reactor with ultrasound coupling for higher efficiency and improved color.
Alternative Context (AOS as Oligosaccharides):
In a different context, AOS can stand for Arabino-oligosaccharides, which are hydrolyzed by enzymes like exo- and endo-1,5-
In a different context, AOS can stand for Arabino-oligosaccharides, which are hydrolyzed by enzymes like exo- and endo-1,5-

Does olefin sulfonate irritate the skin?
As a powerful surfactant, sodium C14-16 olefin sulfonate can disrupt the skin barrier, creating an uptick in water loss from skin's uppermost layers. Together, this can cause dryness and sensitization even from brief exposures.
