ABSTRACT:
This invention relates to a process for producing mono-ortho-tert-butyl-aniline in high security selectivity and at high conversion using a silica-containing catalyst. The reaction is carried out using a fixed bed reactor. Di-tert-butyl derivatives are avoided by maintaining preselected mole ratios of isobutylene to aniline, preselected temperatures and preselected reaction times.
