HCID 3015090Sulfuric acid--aniline (1/1)

Procedure

Aniline and sulfuric acid, in substantailly equimolar amounts are charged to the rotating reactor to form aniline hydrogen sulfate therein. When the charging is completed, the temperature within the furnace is raised to heat the reactor and its contents above the rearrangement temperature. The released water is vented through one of the hollow shafts exiting the end of reactor. The water is externally condensed.
