Abstract
PURPOSE: When chlorobenzene is nitrated with nitric acid in the presence of sulfuric acid, the reaction temperature is set in a specific range to facilitate the temperature control and produce an isomer mixture of nitrochlorobenzene with no side-reactions, which is used as an intermediate of dyes.
CONSTITUTION: Chlorobenzene is nitrated with nitric acid in the presence of sulfuric acid, preferably of 70W90% concentration, at 85W150°C to produce an isomer mixture of nitrochlorobenzene. The nitration is effected preferably by dropping a mixed acid of sulfuric and nitric acids to a suspension of chlorobenzene in sulfuric acid. The weight ratio of sulfuric acid to chlorobenzene is preferably 1.5W3.0.
