Summary:The invention relates to a process for the preparation of chloronitroanilines or chloronitrophenols, which comprises chlorinating nitroanilines or nitrophenols in hydrochloric acid by adding simultaneously separate streams of nitroanilines or nitrophenols and of a chlorinating agent to said hydrochloric acid. The process affords pure products in good yield. An accumulation of chlorine during the reaction is avoided. Chloronitroanilines and chloronitrophenols are useful intermediates for the snythesis of disperse dyes.
