Narrowing of alkylphenol ethoxylate distribution

Narrowing of alkylphenol ethoxylate distribution

The homologue distribution of alkylphenol ethoxylates can be narrowed by using the non‐standard catalyst proposed for alcohol ethoxylation. The reaction is carried out at 180–185°C in the presence of 0·3% catalyst in relation to the alkylphenol. The formation of increased amounts of dioxane and poly...

Zusammenfassung:The homologue distribution of alkylphenol ethoxylates can be narrowed by using the non‐standard catalyst proposed for alcohol ethoxylation. The reaction is carried out at 180–185°C in the presence of 0·3% catalyst in relation to the alkylphenol. The formation of increased amounts of dioxane and polyglycols is not observed.
