WebOct 26, 2024 · Various catalysts were used to catalyze the ethoxylation reaction of C12–14 primary alcohols with ethylene oxide. Alcohol ethoxylates with a ratio of ethylene oxide/substrate near 3 were synthesized. The catalysts influenced the reaction rate, molecular weight distribution of adducts, and formation of byproducts. The … WebApr 1, 2024 · Formulating narrow-range ethoxylate is simpler and cheaper than standard alcohol ethoxylates due to its lower free alcohol content and a higher proportion of the target ethoxylate. Owing to its non-ionic structure, this product is appropriate for anionic & cationic surfactants and remains constant in the presence of acids, bases, and salts.
