Abstract

original image

A novel method used to incorporate iron into the three-dimensional mesoporous cubic SBA-1 materials in highly acidic media is presented. The amount of iron present is controlled by simply adjusting the molar hydrochloric acid to silicon ratio. Moreover, the novel catalyst shows significantly higher phenol conversion and 4-tert- butylphenol selectivity in the tertiary butylation of phenol (see Figure).
