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

Procedure

In the dry processes, aniline and sulfuric acid, in substantially equimolar amounts are charged to the reactor to form aniline hydrogen sulfate therein. When the charging is completed, the temperature within the surrounding furnace is raised to heat the reactor and its contents above the rearrangement temperature. The released water is vented and is externally condensed.
