Influence of alkylation parameters, feedstock composition, and catalyst type on the ortho/para ratio of resulting alkylphenols

Аннотация

It has been found that process time and temperature affect the isomer ratio of alkylphenols depending on the catalyst type. Phenol alkylation with linear α-olefins leads a prevalence of ortho-alkylphenols over the para-isomers, unlike the case of branched olefins.
