実験手順
The classical process for making sulfanilic acid is the "baking" process wherein aniline acid and sulfuric acid are mixed together to form the solid aniline hydrogen sulfate salt (Fiat Report 1313) (1945). In one variant, a batch-type process, a layer of the solid salt several centimeters thick is spread on lead or iron trays. The loaded trays are then slowly passed through an oven or tunnel kiln and heated to above the rearrangement and water elimination temperature. The eliminated water is vented from the kiln and condensed together with any vaporized aniline. When the trays emerge, conversion to sulfanilic acid is substantially complete, the trays are emptied and the cycle is repeated by reloading the trays with additional aniline hydrogen sulfate.
