AI Overview
Alpha Olefin Sulfonate (AOS) production in a sulfonation plant involves the reaction of
-olefins with sulfur trioxide (
) in a falling film reactor, forming alkene sulfonic acids and sultones. The hydrolyzed AOS process requires high-temperature, alkaline hydrolysis (
, pH 12-14) to convert these intermediate sultones—which are skin sensitizers—into hydroxyalkanesulfonates, ensuring a safe, biodegradable, and high-performance anionic surfactant.
