Fatty alcohol ethylene oxide
WebThe actual technology is to convert ethylene oxide/propylene oxide with a long-chained alcohol, catalyzed by a homogeneous catalyst (e.g., KOH). Traditionally, the operation is conducted in semi-batch systems characterized by a low productivity. As the demand of surfactant production is increasing, it is natural to shift to a continuous process. Fatty alcohols became commercially available in the early 1900s. They were originally obtained by reduction of wax esters with sodium by the Bouveault–Blanc reduction process. In the 1930s catalytic hydrogenation was commercialized, which allowed the conversion of fatty acid esters, typically tallow, to the alcohols. In the 1940s and 1950s, petrochemicals became an important source of chemicals, and Karl Ziegler had discovered the polymerization of ethylene. These two developmen…
