About this document
Selective Alkylation of Phenols Process by Stella Aguirre is a document available to read on EtoBox.
This patent describes an improved process for selectively alkylating phenol compounds through vapor phase reaction over an alumina catalyst. The process involves continuously feeding a phenol, alkylating compound like an alcohol, and a minor amount of hydrogen halide gas to a reaction zone maintained at elevated temperatures. This results in (1) reactivity at lower temperatures, improving yield and catalyst life, (2) improved direction of monosubstitution over multisubstitution, and (3) improved selectivity
