Abstract
This invention relates to a process for producing mono-ortho-ethyl- aniline in high selectivity and at high conversion using a silica-alumina catalyst. The reaction is carried out using a fixed bed reactor. Diethylaniline derivatives are avoided by maintaining preselected mole ratios of ethylene to aniline, preselected temperatures and preselected reaction times.
