Diphenylamine alkylated with olefin mixtures containing fractions with varying degrees of activity |
摘要 |
Disclosed herein is a process for the preparation of alkylated diarylamines comprising adding to said diarylamine an olefin mixture containing highly reactive fractions, as well as fractions exhibiting a relatively lower chemical reactivity, in the presence of an acidic clay catalyst at a temperature low enough to prevent substantial deactivation of the catalyst until the addition is complete and then increasing the temperature to increase the alkylation rate of the less reactive fractions.
